I quite often fall on my lessons ie not been going and the rule in my club if you have not been going say for 3 lessons or moreie like a week or two, [bad i know] then replace them as soon as possible so an extra day a week until there all gone.
I have 18 lessons to catch up on, and i know that is very very bad
Last year i was diagnosed with asthma [i had when i was a child, now its come back, and i've started work on fridays afternoons, so thats my excuse
