Rant!!...How am I supposed to not stress when both my sister and my bf's sister are a complete mess and call us to help them with EVERYTHING! This morning I had to wake up super early to take my sister to court because she's being evicted from her apartment.Was on the phone almost all day trying to find her a place and she makes me feel guilty cuz she can't move in with me It's against my lease..I dnt wanna get evicted as well!She stayed all day I cooked dinner she ate and finally left about an hr ago(9pm)..Well Now my bf's sister came to drop off her 7year old son which was here all day as well(bf is babysitting him) at 10:30pm because her and her lame ass baby dad got into yet another big fight(happens every other day I swear) and has the nerve to ask my bf if she can move in with us for a couple of weeks..Ummm No! Sorry but if my sister can't neither can u!Might sound like I'm a bitch but I gotta look out for me and mine first..so go ahead and try and make me feel bad about it at least I'm not the immature one that doesn't have her shyt together and I'm about to have a baby soon Geeeeesh! BTW both sisters are older than me..go figure uggghh Rant over! sorry ladies😏
