I have the same problem with some of my famblee members, specifically my mother in law, one of my grandmothers, and my mother. My mother is the worst one because SHE will start the "let's don't exchange or give gifts, EXCEPT for the kyds" (which leaves EVERYONE out except one sister who has the kyds, btw)which always gets me pissed. THEN, she will send a huge check in the mail anyway. My grandmother who is nearly 90, has been saying, "don't get me anything", and "let's don't trade gifts", for as looong as I can remember, but she always sends a check at the last minute or shows up unexpectedly with a back seat full of gifts and/or an open checkbook as well. The MIL is new to me with this only being the 4th Christmas that I have been exposed to her. While she doesn't do like the others and say "Let's not trade gifts" and such, she must have to buy gifts ALL YEAR LONG, judging by the embarassing number of presents she gives to me and everyone else.
I have decided that this "Let's not trade gifts" and "Don't get me anything", said over and over, year after year, must be some psychological problem rather than a true wish or desire, or they wouldn't keep showing up with the loot or sending the damned gifts anyway! Personally, I am SICK to death of it. I will continue to buy what and for whom I want to and completely ignore their protests of "I TOLD you not to get me anything!!!!", and just walk off when they "start up" with the tell tale symptoms of their Christmas psychosis. This year when the MIL stacks up 20 or 30 gifts in front of me, I will not say that it's too much, you really shouldn't have, you really outdid yourself this year, or any other enabling and cliche' phrases. FROM NOW ON, I will simply open everything with NO fanfare and without comment and simply say, "Thankyou SO much", and be done with it.
Then, I will do what I always do which is "regift" a lot of it. Maybe I am contributing to their mental illness which I have labeled, "Guilty gift givers psychosis" by over thanking or making a big deal out of the presents themselves or saying how I will enjoy each one or something like that, which us what I was taught to do out of politeness. From this year forward they get the one and it will be a simple and quiet, "Thanks so much" (and I might even "mouth it" from across the room, too) and that is ALL. Maybe if they don't get as much attention then their illness will go into remission. If it does, then I can be certain it was an attention getting mental illness much like Munchausens, hypocondria, or preggo related "illness'". I'd like to think that by not reciprocating or enabling them by feeding them with thank yous or extra attention, that I am helping to cure their illness.
I have realized while writing this that the VERY ones who are sufferring from this "Christmas psychosis", are the ones who taught me and others to profusely thank people when they give gifts. Therefore, I have to conclude that in addition to their illness, they have also created a built in "drug" of sorts for it by teaching their young to feed them the compliments. Those moomares are gooooood at what they do as this is obviously a generational thing. I intend to be the weakest link in this gift giving illness and break the chain of insanity.
