Whatcha laughing at ?

There sometimes a reason why someone ask you to do something for them even if they know they are okay with it but then they still ask you to it because of a "reason". Haha huh that really sound complicated to relate to xD So basically maybe something they already experience and they dont want it to repeat . It could be a mistake too...Well, I got something that I really want to relate to that if you get what I mean...

Asallamualaikum ^^
It start with my name. Yes I admit it. it's a beautiful name MashaAllah. That was given from my beloved parent. Ohh yes. So, you dont go around and play with people's name because they got a precious meaning ( if they do as in Islam it have to have a meaning) Yeah because in AfterLife they will be calling you by your name that people have been calling on you. (blabla* you know this I know sorry _)

I usually be like this :

Hello, my name is Nur Irdina binti Mohd Safawi. You call me Irdina.

But now :

Hello, my name is Nur Irdina binti Mohd. Safawi. "by what name can I call you Irdina?" No just call me Dina. 

 After these two things happen I really feel like slapping them :

1. I dont know if I really do like people call me Dina because long ago, I let them call me Irdina. But after going to KSA and entering the real first school over there full of dumb arab girls who like to bully and also some Pakistanis + Indian I just go with Dina. I dont like that school truthfully. "Al-Isra' International School". I use to think that the school was made by Israel xD haha badass ~Yeah~ Sho My name was beautifully spelled Nur Irdina and they suddenly make their own by calling me "Nur Irudina" I was like "Bitch who really you are calling ? " And I got fed up of fixing them since they know it and I still remember they laugh and smile while saying it. I just have to step up you know. It's really annoying. I cant stay so quiet while they are changing the meaning of MY NAME. I do remember actually what really happen and it ends with a cry. There's this at least one kind girl who just comfort me . her name was Diana or something like that (lol) and she said she went through it and just chillax . haha :) hmm... So when I entered a new school, I just told them this short nickname "Dina." If they cant evn pronouns that properly, I dont know what I would do -.-"
2. I wud really feel great slapping this girl . Ugh . I dont mean that I have grudge on here but I dont like her anymore. She move classes and in Malaysian Public school there would be like wanna be scout (didnt I tell you this yet? haha) so PBSM (wanna be doctor or nurse), me . huh. with her. It is just checking who's present and a Chinese girl was reading it. So when it comes to my name, she really didnt read it greatly and I dont mind that but suddenly that girl -.-' just start laughing like crazy and sooooo i mean like out of her mind. =.= ugh . *bitch. k.

k. So you see how I get really sensitive about saying my name wrong. It's okay once but if too many times going with a laugh. I'm coming bitch**.
