answer:2 reasons I can think of. The first is just to fit in, really. Pretty much everyone wants to feel like they belong to part of a group. They want to fit in somewhere and not to be alone. Maybe they think if they act or look more like you do, you’ll be more accepting of them. Second reason is that maybe they just like your style. I suppose there could be many other reasons as well. But don’t let it bother you too much. After all, they say imitation is the sincerest form of flattery!
