So, there's this dude at my church. I think he may be autistic or something (but, high-functioning, and he comes to church alone.). I've never really spoken to him, like at all. Not because I don't like him, or something. Just because I'm shy so I don't go up to strangers. Anyway, out of the blue he just came up to me, said hi, and hugged me. Now he does that every week. It's not a big deal to me, but it makes me uncomfortable, because (like I said I'm shy, and) I don't prefer hugs from anyone. Also, I'm a teenager, and he's like 20s or something. Should I try to politely tell him to stop or just deal with it? Not sure if I'm overreacting or something... Also, sorry if I offended anyone. That wasn't my plan..
