We all have expectations of others even if we should not. Perhaps they are not really expectations but they are more like ideas of what we would like them to be like. Sometimes when people do not reach one's expectations its not really that they disappointing but maybe they were never really capable of being whatever way one may want them to be. It can be hard to accept people for what they are capable of instead of what we would like them to be. I know this sounds like a cliche but it is so true.
