A fairly ' normal' client, as he was getting dressed after I had gently told him the hour was now up
Him: Oh yeah I should have asked earlier but you do get tested don't you?"
Me: Yes I Do, do you?
Him: looking at me rather oddly, er um
Me: Well you can catch things from oral without don't you know that?
Him: Err ye uh umm
I'm still undecided whether it was an attempt to lash out at me for not letting him over stay or whether he genuinely is unaware of risk
