i remember my old-T would allow me emails, and always made an effort to reply. one week he didnt reply at all, and i was a mess come appt time. he apologised about the non-reply and said he'd started replying but run out of time, and thought it would be better addressed in session where he could clarify etc. he even offered to read out the beginning of his reply to me.

i just spent the whole time thinking - but why couldn't you have just dropped me a little note say "hi deli, have read your emails but am too run over to reply this week. let's talk in session".

so maybe your T thought that this tiny reply, this acknowledgement, really, was better than nothing?
