Why do people assume things and never ask?

I had a very good friend say to me the other day that the reason i was not asked to go some where was because they assumed i would be busy? Yet other times then they must have assumed i was not busy,is that the case.I hate people who do not ask things about anything and assume things.I looked in my diary last night and i saw some dates that got written in my diary yet i assume i can cross a few of them out now as the follow ups have all been done for the appointments,i hope i assume right.
