Why?!

Oh my word! Every time i am planning to stay home go do nothing because I am physically & mentally tired, my sister has to ask me to go let her dog out. Today is the ONE day I get to stay home all day & just rest, & it’s not like it takes a lot to let the dog out, but it means I have to get dressed, have to drive to her house, let him out, then drive back home, & every time it’s (f-ing) last minute…they left their house at 8am, the other team didn’t show, & the coaches were calling other teams to play, so WHY didn’t she call or text one of us sooner?!?! Why does she wait till now, & text my sister, who’s already at work, then text me & is like he has to go out now! I’ve been working on cleaning the house because we’re having a party tomorrow, & I get tired easily now, on top on constantly being in pain. So for me to actually do this is quite the chore. And of course, it’s last minute. I want to say no so bad, my my sister is at work, my parents are at something for them, & can’t easily leave…so as per usual, that leaves me…WHY ME?!? Why is it always me?!?!
