Who Really is the Guest?

Okay, so today Rona(Banana's Friend) goes to our house to hang with Banana, who's my sister by the way. I get this feeling everytime She's around. There was only one day/night where banana was okay with me. she wasn't a bad ass to me! but after that she's back to this being all snobby and arrogant and fucking rude to me! I really don't know what brings her to be like that! I'd hate to think that rona's a Bad influence but come on! every single time my sister becomes good you come along to ruin it. you do drugs and you drink all the time. you also smoke. I just really hope pray and wish that my sister's not doing the smoking and drugs shit. or else it's whole new diff. story here. Banana has the defensive and Possessive feeling with her friends. She doesn't like sharing her friends. Even with our cousin yzel she only gives me time with her if it's about nikki..hmm.. or maybe I'm the one who's possessive with my friends.. but actually no.. cuz I like her being friends with them.. I even encourage her to befriend them and be nice to them. It's just she always becomes a bitch whenever her friends are around. well she is one spoiled brat who gets what she wants but a BITCH is whenever she's around with her friends. La Salle may be good for her studies and shit and her party life and connections in life but she's not having herself change for the better. She keeps this act no one will want to be her real friend when she's down. she's very judgemental of people and even says "gago" to our mom. I don't know also when will she stop making gastos all my parents' money away..for shoes , dresses and things that are way to expensive for our lifestyle. I really wish she'd do this one thing for the family where she won't make any gastos for a year. taht would do a lot for the family. and I won't be a hypocrite , I won't make gastos sa food nadin. that'd probably help me with my figure. that's another thing I have to worry about now. but let's not get off topic , I got so pissed off by her kanina because I was asking her this one favor where all she has to do was to transfer songs to my ipod.. just like what she did to me a week ago.. oh but no.. all she can say is "gamit ko computer e" i mean what the fuck??? how come you can crash in me whenever you NEED it??? I just did what you did to me and now all of a sudden you do the right thing? I mean come on?? are you for real?? You know what? I still have to put my guards up with her. I can honestly say that I can not trust Anyone right now.. it's hard. No one. I'm just full of hate for my sister right now. maybe in the morning not anymore but I am still building my wall between us. she thinks she's always right and she's always clean but NO. YOU are NOT. fuck you! you can't be that perfect dear sister! God did not create us that way. Someday, I dream someday I get over you. lalagpasan kita! I PROMISE MYSELF THAT!
