Goodbyes

It's funny how quickly people come and go in life. They'll be in yours one moment, and gone the next. Sometimes it's for the best, but other times can be quite hard. It can change your life forever. Someone can come into your life, brighten it up, and then leave - again, and again, and again.. But in the end, you're left on your own. Why does this happen? That's what I want to know. They say everything happens for a reason - does it? And time heals all wounds - no, it doesn't, believe me, it doesn't.
