For example, if someone wanted to swap a shift with me for prior arrangement, and I could swap, I would. Some people will just say no to be awkward, what's the point? One day when you need a shift swap, you won't get it back. I just hate it when people expect the world to be nice to them when they're not nice to the world.
Does it make me too selfless to think that way? Am I too much about others than about myself? I don't know. But what I do know is that it doesn't take much to be a decent natured person.
The best way to try to solve arguments it feel is to put yourself in their shoes. If that was you, how would you feel? Would that make you angry as well?
Best example for this is relationships. One half does something wrong, and gets angry because the other half is angry. It's fair enough if they viewed it from their eyes. If they can't see this, they're an awful person and not worth being with. ;-P (this is probably why I've been single for a year...).
I just feel sometimes people need to step out of their own shoes and put on someone else's. Doing something to help someone else out gives me so much positivity in knowing that I've helped them out, or they can go to the concert they've wanted to go to cause I've swapped a shift. Give someone a little lift and it will go a long way!
