Natural pessimism?

It must be my natural pessimism, Although I believe very much in optimism and I preach it to all those people who see the glass as being half empty.
Every time I'm on my way home from a REALLY good time, the kind of good time which makes for memories you talk about years later, in conversation starting with " hey you remember that time when we went to...",l I think of how soon, it'll come to an end.

This is life after all. if everything was one, big happy holiday, the point would be lost and I wouldn't even be able to enjoy what i can't have all the time. But life gets so complicating so FAST, it's like a flash of lightning leaving you with this fading feeling of forgotten euphoria, and a burnt ass that you have to deal with.

Geez.
