i'm wearing a thin t-shirt at work and i know the air conditioning is going full blast (because i can hear it) but it's doing me no good! so sorry you’re having the slipping problem! this can be a fascinating experience for those not used to such treatment. we would love to see you. the kind of articles i write or the content i deal with, requires massive amount of reading apart from real life experience. i ask the students’ neighbor to “go get an absent folder” and put it on his or her desk.
