My sister doesn't really realise that her decisions AFFECT the whole family, she has been going to parties , alot of parties recently, as she always asks around for transport, we are okay, with her going for parties, she just called to say that the girl whu brought her to the party can't bring her back, isn't it already PREA-ARRANGED?, that this person should bring her back?

My parents and i were planning to go our for dinner, as shes eating there, now it has to be put on hold because she hasn't found transport yet and may need us to go fetch her, like if she can't find transport, then she sould just tell us straight, we will make arrangements, now she says she unsure on wether her other friend's mother can bring her home, and because of that, we are now DINNERLESS..

i guess this is so, because we are relyin on otheres, so i DARE not complain to mum, or i might get TICKED OFF
