No it doesn't bother me! I love the world ! When a پرستار posts on my دیوار an image about love یا friendship, I like that. As they say..."Love makes the world go round"!
It depends. If they're your friend on here, then it's not wierd. I love my دوستوں (in a friend way) & I say it when I want to. But if they don't know you, & you've never spoken to them in your life, یا had any interaction with them on here at all, than yes, it's creepy.
