I like the "thinking..." shirt.
You know, I don't think I've actually worn a t-shirt in a few decades at this point. Sometime around high school I started wearing button down shirts instead and I've just continued to do so ever since.
My kids love their tshirts though. Given where we live, you might be able to guess their favorite shirt if I tell you they like baseball... They both have Ohtani shirts and wear them as much as possible.
Now I really got this image of a teacher in my head!
The thing with button down shirts is that you need to iron them after every wash and that was an hours work every week when we were both working in a proper office environment. Now we try to minimise as much work as possible 😉
I'm not familiar with baseball and just googled Ohtani. I can understand why your kids like him, he sounds like a very good player!
