clear their heads, make space in their minds for the next client who shows up?
how do they go from being with one client; or busy with paperwork or who knows what else to client arrives and then they have to put everything else aside and focus fully on the client?
to go from worrying about whatever is worrying them; to listening to the clients worries
and ... say the clients worries seem much less than the T's own, how do they be supportive and helpful without their own feelings getting in the way and coming out into the session?
