<human>: My birthday is coming up in a short while, and my mom mailed my gifts to me since we don't see each other very often. Naturally I opened them ahead of time because... well... gifts. My family has always been very big on wishlists, and birthdays are no exception, so of course everyone made me send them a wishlist of things I'd like for my birthday. Here's the problem... my mom got me something that I've never hinted towards wanting, and it isn't like me at all. I don't want to go into too much detail, but imagine you knew a person who hated cars, never drove a car, never owned their own car, and you got them a set of windshield wipers for their birthday. Not only that, but the windshield wipers are lime green, which you know is a color they dislike. That's the predicament I'm in. The gift she got me is so out of left field that I honestly just don't know what to do. 

When my actual birthday comes, she'll be expecting me to say thank you, etc. and I do appreciate her getting me gifts (I'm constantly telling her she doesn't have to) but I just don't understand why she got me this... 

My family is also the type where saying "thanks, but this isn't my style" or something similar is seen as incredibly offensive/upsetting/insulting. I don't know what to do. Should I lie and tell her I like it? I don't want to receive more in the future. Should I tell the truth and have her be upset/angry with me? 

Part of me is almost insulted because she should know me... she should know that this gift is actively against every thing I like, more or less.

Can you condense the text into three sentences or less?
<bot>: My mom got me a gift that makes no sense. Telling her this will upset her. What should my reaction be?
