mine says "well we need to end in a few minutes" or some variant of that if in-person session,and then i usually pretend i didn't hear her and continue speaking or hold tighter to her. if it's a phone session she says that or "well i am going to say goodbye now," at which point I curse the medium because a cell phone prevents me from hugging her to prolong the session just a couple more minutes...
oh she also sometimes says "we can talk about this more at the next time.." or "we need to end now " and i scowl at her for being rude! many times my sessions have gone over many minutes so I can't complain really. But I mean, of course I am unhappy about having to leave T!
