It may well be stalking but it is not unusual. As long as you do not make any derogatory remarks just enjoy yourself and, if you feel up to it, befriend them.
I do it. I like to try to find out who someone is REALLY. People are post their lives publicly. They know people are looking. In reality i think everyone wants/needs attention. Thats how they get it. From the whole world. Even us!
just a little bit, why not send a friend request?
No, just enthusiastic.
Yeah that's pretty weird.
Well you should consider why you're stalking them without even friending them. Do some inner reflection on this one.
