bird call

I forgot to tell you, there is this house that seems to be full of guys on my street, they are always working on their cars and stuff outside...well yesterday I was walking home from school, and I passed their house and as soon as I was on the other side of it I heard this whistle. I thought it was one of them whistling at me but I didn't turn around because that's ridiculous. You know what though? It kept getting closer and closer and I was like jeez these guys are so trashy but I was really close to me house and then all the sudden a bird flew past me and it was the one whistling. I guess it was out to pick up some girl birds.
