I don't normally take holidays outside the normal holiday times - Christmas/New Year, Easter, and over the summer months, when T is away as well. I don't have to pay for not coming to sessions when he is not working, obviously.

But yeah, I had to pay for the session I missed due to a work trip two weeks ago, which I had told T about two months in advance. But seeing as I don't have to pay for the sessions I go to, I'm not complaining
