Okay. Now you've got me crying. My "boys" are 30 and 22, but sometimes when I look at them, I see what Mike sees.

My father was exactly like this at my wedding. It was difficult to find a photo of him smiling.

I was trying last night to work out what that lovely image in Sunday's strip -- Mike sitting stunned on the Walden porch -- reminded me of. And then I remembered: it reminded me of B.D., also stunned on the porch, during the fall of Saigon in 1975. How many of these characters have experienced the highs and lows of life sitting in this spot? What a truly remarkable life achievement this strip is; no classic 19th century novel can beat it for narrative and character.

Toggle's expression in the second panel of today's strip exactly captures how I felt when I first saw my bride on our wedding day last August. Thank you.

I notice that Toggle doesn't stutter when he texts.

I keep being drawn back to those eloquent images from Sunday. Yep, this one will be remembered as one of the best, most meaningful strips ever penned by GBT.

Very cheeky strip today, GBT. Reminds me of the punch lines to many a locker room joke I heard in high school.

Today's strip is so very funny and real! Thank you.

Garry: As a reader of Doonesbury for at least 40 years now, I've always related to Mike, but never more than yesterday. I have two daughters in their 20s, and your Father's Day strip showing Mike so pensive about his daughter's wedding touched me very deeply. Thank you for not only that poignant moment but for decades of thoughtful social commentary and biting humor.

I don't know if anyone else has pointed this out -- and it's not that it's preventing me from thoroughly enjoying Alex's wedding, but it's driving me crazy! Joanie didn't get married at Walden. She got married in Lacey's (parapharasing her mother) "fancy-schmancy" townhouse in D.C.

Okay, Leo, here you have the Three Main Rules of Marriage, in a nutshell: 1. Men always have the last word in a discussion, as long as they say "Yes, dear." 2. When men demand hot water, they get hot water. Doing the dishes otherwise is not reasonable. 3. No matter what, women always end up kneeling before men. And when they are kneeling, you will hear them say "Get out from under the bed!". (Sigh.) Best of luck.

Leo's ready for marriage. Having been in the military, he has rules #1 and #2 down cold.

Sunday's strip adds depth and dimension to both Mike and Walden, after 40 years. Simply brilliant.

Mike's expression says it all. We fathers have all felt the same at our first daughter's wedding. But Mike has prepared his daughter well. The future for that family remains in good hands. Thank you for this truly poignant moment.

Mike ol' buddy, I think we're all just about as shocked as you are. They grow up so fast, don't they?

On reflection, I am not sure what stunned Mike so.  Was it seeing how grown up Alex has become, or that she has never looked so much like her mother before?

As a wedding gift to honor Leo and Alex I'm donating my miles to Fisher House ("The foundation uses donated frequent-flyer miles to provide airline travel to reunite families of the wounded and to enable our wounded heroes to go home to convalesce.") The Fisher House web site is easy to use, and airlines that support the program are listed.

I remember that look on my dad's face on the day of my own wedding. I didn't truly understand it until we got the photos. I looked exactly like my mum, who had died three weeks before; I am in awe of how my dad managed to get through the day.

When Mike saw Alex in her wedding dress his eyes changed. I hope they don't stay that way. My grandpa has Alzheimer's, and that's how his eyes would look in the Doonesbury world.

Aw, man! Way to make me cry! She's gorgeous.
