I think it's just weird!
My mom is always checking up on my facebook. She's not on facebook herself but she makes her friend's daughter show her my facebook. She'll call me afterwards to ask me why I gained weight (I haven't) or yell at me for shopping ("I've never seen that shirt before"). I'm used to her by now, plus she's just my mom.
However recently khalti (maternal aunt) requested me on facebook. Why did facebook give her an account? I mean I don't have anything bad on there but like a lot of khalat out there she's a bit on the judgemental side.
I couldn't justify not accepting her but now I feel like my private space is being invaded.
