I 100 per cent support thank you cards, both in theory and in practice. But also? Life, man. After your kid has a birthday party, you've got to get the cards, track down each guest's mailing address, find stamps, and if you're extra enough to let the child write the notes herself, oversee the project for days. ("How do you spell Makenzie? Oh no, I messed up. I'm going to start over.") It is a process. I've noticed that many parents are now skipping physical thank you notes and sending mass "Thanks for coming!" messages, and I get that, but to me, it feels a little impersonal.
