I've been seeing this girl for a little while now and last night we were just about to have our first kiss in her bedroom when I sneezed right in her face.

There was a big string of snot down her cheek, but it looked really funny so I burst out laughing. She got mad and told me to go home. Now she won't answer any of my calls and nobody answered her door when I called at her house.

What can I say or do to patch things up?
