I usually get involved in most things, but if my Vimvie needs to make a phone call I tell her she must do it, it will build up her confidence as you say, and I also think it can make you look ridiculous if you need an appointment and you get somebody to call for you..

It's nice to hear your becoming more confident, you've got to stand up and be counted when you live in Britain! Shyness can be a very attractive attribute in a woman, it wont help you get on in life though..
