Mirror assigment

As i started looking at the mirror my first reaction was fixing my hair, then i looked at my teeth and "checked my self out", but after 30 seconds i started to see blackness and i did not think of absolutely anything. Until i started to wonder why are we alive, what's the point of this what would happen when we die or where were we before we were born, i mean we can't just pop out of nowhere we have to come from somewhere. Right after i had that thought i forgot to why i was looking at the mirror and remembered that it was for an english assignment so i fixed my hair again and the 5 minutes flew by.
