I have been wondering this for some time. I have noticed less and less people say thank you for a thoughtful gift. They are not obligated to say thank you, but seems kind of rude to me. We had 3 baby showers at work. One person mentioned a thank you to a small group of people. The other 2 said absolutely nothing. One of those co workers left and people put money in the card for them as a good luck/new start of life sort of thing. Maybe I was petty, but didn't put a single dime in that card and only signed it. Since my baby shower gift went unappreciated, why should I give them more? Is this the new norm? Just wondering if this irks other people as much as it does me.
