if it's your place, tell her she can't stay. Not your fault she can't keep her legs shut.

Its your mum's house, not yours.

This person is from the UK; over here we refer to 'our house' or 'my house' as the family home, not necessarily who owns it. Because OP's final exams are in May and June, it's likely that she is talking about her GCSEs - she's 16 and it's her mum's house. Obviously, her mum's decision would be final, but you'd expect a certain amount of consideration on the part of the parent :( OP, since locks on kids' bedroom doors aren't usually the done thing in the UK, take the advice of an earlier poster and go to a library or cafe to study. Seriously.

not your house OP, STFU

how old are your sister's children? don't they miss school or something? or they don't? ... learn to love kids? FYL. really. FYL.

You can complain when you pay for your own place. study elsewhere. I'm sure when you get knocked up (or knock someone up, i cant tell if you're a boy or girl) you'll need your mom's help too.

Either way, get over yourself and deal.

Go somewhere else to do ur stuff. Pregnancy is hard to deal wit alone n she just wants support from ur mom, u ain't poppin out a kid so b thankful for that lol

Sounds like you are old enough to spend time some place else!
