Summer Training Program

Hey people,yeah it's been a long time since i posted,nearly a decade,just joking,so am in the university and am taking only one subject in the summer which screwed nearly all my plans for the summer,i haven't even swim once during this summer and that's huge for me,and of course as you know the summer where all the S*** happens,like this last weekend,my PS2 lenses are burnt because i gave it to a friend of mine and he appused the PS2 until he burnt it,and my TV is broken,and tommorow or after tommorow my aunt and her husbund(they live in the US) are coming to stay here with my other aunt and her husbend and kids and of course my grandmother,so you're talking about 16 people people together living for about a week,and don't get me started at my cousin,if they were my age that won't be a problem..but all of them are kids and i HATE THESE KIDS!!! they are like little demons keep respawing in your room even if you told them to get away from you....they go through my stuff....even my personal ones,they use my cell phone,my pc,and even one time they broke my PSP!!! arggh!!! but if say anything about it my father would kick my butt...because they are guests,when am a guest i don't do these stuff.

Anyway,about the topic,yeah i have three summer camps,one as the topic says is a summer training program about palestine and its culture with field trips and such,but i have a conflict in my schedual,you see,i have my subject from 2 to 3 oclock and the program is from 10-12 pm,and from 1-4 pm.....if i skip i will fail in my subject and if leave this one hour and seen it i will be disqualafied from the summer program,my life is complicated....what should i do people,i'd love to have advice about this whole thing.
