My T laughed at me once - don't think T meant to be horrible, or realise exactly how sensitive I am to being teased, but it really hurt. Took me a few weeks to raise it (could only do it by e-mail) T was so sorry and actually I think me raising it was a good thing at that point as I do think it led to me letting down my barriers slightly in that T listended, acknowledged and hasn't done the same laughing thing since.

For me it is the bit about them being human and that the only way they can gain their experience and build on their skills is through work with clients and therefore they can all make mistakes - I've read somewhere recently that the difference between T and your parents is not that T's don't make mistakes, but it is what they do after the mistake that is important.
