I like that my T is older than me too because it allows me to see her as wise. I'm sure IRL she doesn't have her shitte together as much as she seems to in session but I think I'd feel a little self conscious if I were a mess and some young T apparently had it all together.

However I bet that age is just another one of those traps we fall into where we think we have to have a particular thing in common to have our T get us. The beauty of a great T is that they can hear you well enough and have enough wisdom and empathy that they will get you much of the time even if they haven't shared your particular experience or come from your demographic. No T will get you all the time and that's okay.

Having a T who is willing to look stuff up in order to understand you better or explain something to you is a great thing. I wouldnt want a T who feels so sure of their knowledge that they aren't regularly reading up and looking into stuff. Certainly it's nice to have someone with a solid knowledge and experience base, but a willingness to admit what one doesn't know and an eagerness to learn it are really great qualities in anyone.
