I Am Prone to Inappropriate Laughter

On A Date... I was probably 17 and went on a date with a guy who had been my friend for a long time. He was really fun and when he asked me out, I thought " why not ? " he's always a lot of fun. I was obviously a little nervous and I giggled through the entire date but he was a funny guy . We went to see one of those Alien movies it was like 1986ish. We get through the whole movie and at the end there's a part where one of the andriods or whatever it was dies and this milky substance starts shooting all over the spaceship . I'm not sure why but I busted out laughing at this part. IT was a fairly intense part of the movie. I laughed all the way to the end of the movie, All the way to the car and all the way home. He didn't ask me out again after that .
