Don't Rush Me....!!!!

I hate it when people just treat me like a servant. Asking to do their chores and asking me to deal with their problems. Like as if i don't have enough on my mind to keep me busy. Even worse scenario is that when i don't do it well or right, i get scolded like as if i am supposed to do it for them. Come on, it was like a favor that i am giving you. If you want it perfect, then do it yourself! Don't rush me to finish it so soon. Don't ask someone to do it and just throw tantrums around when it's screwed up. I just feel it is unfair. Then when i do it wrongly, they make me feel even worse than i have already felt. It's not like i want to right. Maybe lending a helping hand is not always rewarding in the end.
