There is a man who gets on/off the same bus stop as me, then he lives in one direction and I live in another. I have seen him with his wife/partner and children in the local area. I have no idea what his name is or anything like that. I have never sat next to him, I am usually at the back and he sits at the front. I have never acknowledged him, ever, not even a friendly nod of recognition. I have seen him getting on/off the bus perhaps about 10 times in the last year, so it's not an every day occurrence.
Ok, now the weird bit. He has sent me a friend request on both Facebook and Instagram! Why? I am also a bit freaked out that he was able to find me/possibly looked for me on there. I have both set fairly privately, so only my name and profile pics can be seen on FB and only my user name & a generic pic on Instagram. No idea how he knows my name to find me in the first place, we don't appear to have any mutual friends.
AIBU to find it a bit weird or can someone offer up a reasonable explanation?
