Praise where praise is due

Today I had to review my mentor's performance during my school placement. It's been a tough few weeks and I haven't found it easy. My mentor has from day one told it like it is. She has been completely fair in her assessment of me (not easy to do!) and has tried hard to make sure that I have been able to do what I needed to do.
What more could she do? especially on top of all her other work. So I gave her practically 'top marks' - and told her why.
I have never been made to feel in the way - when I know I must have been, just by being there interrupting her routine. In fact I have felt very welcome and at home in her class and for that I am grateful.
