People Suck Sometimes

How can you tell if people suck? You can know someone for years and not know they suck! Why can't we tell people all our downfalls right away when we meet them. Then if we suck... they can prepare themselves. Certain things that suck for some people don't suck for other people. Some people think everything sucks. I'm usually fairly optimistic... so if I say someone sucks... THEY REALLY SUCK! SUCK BAD!
Today someone in my life SUCKED BAD!
Now they are not in my life anymore. Hip hip hooray.
