“Why are they creating more problems, don’t they know it already how to do it?”
We often think that why other people can’t do a simple task? And require us to guide them or to work along with them.
The answer is, yes they don’t know how you want them to be done, because we are not psychic or Prof X from X-Men who can read other people’s mind.
Even though we often work together with someone, it doesn’t guarantee that they know us outside in. Well, of course when there is some time constraint involved in the project, it’s easier for us to get frustrated. Don’t get upset when that happened, take it as a chance for you to know your partner better. To learn that there is something new about them like when we work with them for the first time.
Or how do you deal with this situation?
