Expectation Vs. Assumption

Ok... TODAY just like an other day... when I have again a reason to cry..I sat down a lot of stuff is coming into my mind... and then it came up: whats the difference between Expectation and Assumption? ... and I thought about it and I thought about it... and then I thought ... Why not write a blog on it... Well.. Yeah.. So I thought and thought and thought about it and ... .Expectation:
is something that you WANT to happen...but you are NOT sure that it will.The dictionary defines it as:Eager anticipationBelief about (or mental picture of) the futureWishing with confidence of fulfillmentThe feeling that something is about to happen.
Assumption:
is something that you think WILL happen...and you ARE almost sure that it will.Something taken for granted or accepted as true without proof; a suppositionA statement that is assumed to be true and from which a conclusion can be drawn.A hypothesis that is taken for granted
So....wrong assumptions lead to angry regret and wrong expectations lead to sad dissappointment...
Hmmm...Does this make sense?
