My sister is like this too. I feel like the least of your worries is whether your mother or siblings are looking at your Twitter. It's Twitter for ***** sakes! And if she never visits or calls, it's not really a huge deal.

Another example as to why I'm not having kids

That would hurt my feelings. But I would also back off and let her make the first moves from now on and if she doesn't then maybe it's for the best. Though it would still hurt. A lot.

Passive Aggressive level at maximum. For both of you.

You said adult child- give her space.. Don't let your parenting skills burn a bridge between the two of you- not all children will choose a road less traveled. Stop being nosey, it will only engage in resentment.

I have a sister like that. My mom has done nothing but try to help her, and my sister completely cut her out of her life. She's got a screw loose, and one day when my mom is gone she's going to regret it.

Ngl, you probably seem a little bit creepy, dude. Like. That would creep me out a lot.

it could mean your an overprotective mom, there might also be stuff you dont wana see on there, and, WHOS BEEN PRETENDING TO KNOW YOU?
