Truly said, the time they are wasting can be used for betterment of someone else.
Yeah... that was one of the main messages that I wanted to say... There is always a better way to use our valuable time...
Showing too early is not waste of your time but waste of their time also but may be they have lot of time and nothing to do.
Oh, yes... this is a case very often... Some people have too much "spare" time, and they think if they have, that everyone else has... lol... :)
