I never knew it was a bad thing

I just realized something about me... And it makes me look like an idiot or a doormatt.
I'm a people pleaser, I can never say no to anyone! Lidarajat inno I can get in trouble for it.
Marra, we had an English test w my friend didn't study so he asked to solve my paper -but not write my name- then we switch papers... I said yes!!!! then I thought "WTF... I just agree'd to do something so bad that if the teacher saw us he would give me a 0 on the test" I freaked out.
Then, when the test started...I was sweating...my heart pounding really hard...my hand started shaking, anyway I finished the test without writing my name, I looked at my friend and he looked at me...the class was silent. I nodded my head (doing that made me feel like i was a secret agent on a mission or sumthin' :P) he raised his hand. "what the hell are you doing????" I thought to myself. "Ostaz, momkin a36y nagadi malzama???" He said. The teacher said "ok".
so I reached my hand and took it ( i had a very weird look on my face cuz i didnt know what was going on, he looooled but the teacher didnt notice... thank god) almohim, When I put the malzama on the table I looked at him whispering "where is the paper??" he pointed at the malzama looking nervouse N' stuff cuz he didnt have a paper on his desk, so I feaked out and quickly grabbed my paper and gave it to him and the whole class saw me do that bas al7amdillah alOstaz ma shaf :D:D and finally we switched pens and I finished solving the other paper exactly when the bell rang!!

Anyway, I will never say yes to ANYONE anymore
