There's an ant on my wall...

There's an ant on my wall, lets call him Griffith for the time being,even though the only job a male ant has is to mate with the queens in the colony.
Anywho.
Why is he there? He's nowhere near his buddies. Is he searching for food?
should I kill him? There are plenty of reasons why I should let him live. There are plenty of reasons why I should kill him. This reminds me of the time Silvia, Mario, Alex , and I were eating at Hometown Buffet. It was truly a magical moment, there was total silence at the table after a good laugh. Then, all of a sudden Alex gave a random comment as we ate, "10% of ants are gay". I didn't know wheather to spit out all my food on Mario's face or to choke on my food.

Back to the ant, it's still there. If I kill the ant there would just be a smudge on my wall, then on my hand. I think I should let it find it's way out but...nahhhh!

Thats what Darwin would have done.
