But but but...

You could call and say 'this isn't an emergency but I've been feeling fragile is it okay if I talk to you for five minutes or so?' Then your t knows up front why you are calling and how long your are wanting to talk to them for and they can decide. (Five minutes can easily become 10 or 15 but you should be sensitive to their wanting / needing to get off the phone). If they say 'no' then either they are busy or that is their general policy, if they are happy to talk to you then that is okay :-)

I'm fairly sure that would be appropriate (if you only call numbers they have given you / they know you have) and you call during normal waking hours (preferably avoiding meal times) etc.

I've emailed some... I love email. I mean I LOVE email. I still email a couple of my old t's actually... That is pretty cool :-) Not very often but occasionally. Used to email a couple p-doc's too. Had some terrific discussions via email... Once they get a hang of how to take parts and quote them...

It can be a great way to have a dialogue IMHO better than RL
