OP here... I agree and I was gracious and always thank the gifter, of course! I even said in my OP that it isn't a big deal, I just find it weird.
Now....when it comes to "its the thought that counts" I sometimes wonder "What WERE they thinking???" SIL gave DS a tin of candy for Christmas one year...when he went to open it she said ..."Oh, don't eat it! Its probably really old, I got it at a Thrift shop." Really??? What was the thought? And what does it count for?? The tin was nothing special...nothing that pertained to anything he was interested in. I guess the thought is that you are obligated to give a gift...and you don't care enough to find something suitable, or even edible.
