I think Expectations is a good thing because when we expect something from someone It will be late it but when we knows that what we expect from our friend this excitement is also too interesting from the after 30 or you can say better for status like I can take you an example that like festival when we know that in a date that will comes but when it across with our life you will get sad so excitement is good when we have some good times with our friends when this friend will go far from us we will get worried and being very sad and miss the old days..
