A: When you needed someone to feed your cat, I was there.
When you needed someone to help you find new furniture to replace everything that was stolen when I forgot to lock the door when feeding your cat. I was there.
When you needed someone to take you to the hospital when your substandard new furniture collapsed and you broke your hip, I was there.
When you needed someone to have sex with your girlfriend when you were in the hospital, I was there.
I think it's safe to say that I am the most reliable friend you have.
