Wandering the grounds of a school.  There was this guy - reminded me of one current co-worker - whom I may have been following around (out of feeling Insecure) - who went into a classroom.  I went to follow him, but got that this was a mycology class, and wasn't *mine* - so I either didn't have to, or oughtn't to lurk there. So I wandered a bit by myself during the interim.
