First of all, you shouldn’t hook up with anyone at the office anyway. If you did, prepare for damage control. It was fun while it lasted, but it should only last one night. You don’t want an office holiday party hookup to carry over; most importantly, you don’t want her to try to transform a one night romp into a relationship. You have to kill that noise as fast as humanly possible. Before she even thinks of mouthing the phrase “when can I see you again”, nip it in the bud with these post-holiday party hookup guidelines.
