Endlessy Frustrated by you.

I'm fully aware that i should be grateful, because I'm lucky to have you. Yet sometimes I find it hard, because you make it seem like you'll always be there. By now i should already know thats not the case. I know i shouldn't take you for granted. Even though sometimes I do. I shouldn't get as mad as I do. But I still do, just cause I think your gonna take it. Which i guess is wrong, cause there is no doubt that i use you as a frustration outlet. Which is bad. It's just, technically you have the power to hurt me most. You're the one that I'm closest too and feel most comfortable with, i suppose. So everything you do, hits close to home so to speak.
Meh. you frustrate me endlessly.
But I'm sorry I cant help taking you for granted.
