Commenting because I feel like you sometimes. Grumpy and your immediate response is to shut down anything "silly, dumb, or just don't care about" with some glib response.

While I'm glad you have a good memory of your son, and I'm sure there are many more to come, I'm SUPER IMPRESSED you stopped yourself and recognized your behavior.

I've been working on trying to catch these glib responses and trying to stop being a "fucking asshole" to every opportunity to make connections with friends and strangers. I know what it feels like, and if you're like me you hate that feeling afterwards knowing your inconsideration probably hurt and now you feel like shit too, goddamn why am I this way, etc.

Just... props, dude, you know what's up with yourself, your son, and know how to recognize when your automatic response is going to make things worse.
