Sneaking away

My first year of teaching I worked out in a trailer separate from the main building.  Between classes I usually went outside (weather permitting) to make sure that people went between the two building properly.

*Two students try to sneak off behind the school most likely to go have sex*

*I yell at them to get to class and they reluctantly walk towards the school entrance* 

Other student just coming out of the building: "Why you comin' over here?  Did you forget a condom?"
