I just really want opinion on this...am I right or wrong to be pissed?! Please answer?

Yes. You had to use the restroom. Your sister thought about herself.

She should have gotten your drink. If she had to use the restroom, you probably would have gotten her drink--and waited. She is your sister.

Don't stay mad at her long.

Get over it. The event was simply about communicartion.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
