Squash skills

Well it's been over a year now since Mosh started teaching me to play squash. Mosh swore a couple of times today when he missed shots, so progress has definitely been made.
We don't play with any degree of regularity and I won't play a full blown game yet because the prospect of being soundly thrashed would be too demoralising.
I can get my trainers to make that squeaking noise when I run around but flicking the ball up with the edge of the racket so I don't have to bend down to pick it up needs work.
Mosh still flinches whenever I'm at the back of the court returning the ball and he's at the front. I've only hit him four or five times, OK, so there was one occasion when I hit him twice in as many shots and he got suspicious that it wasn't accidental. Squash balls make impressive bruises.
I've also perfected the art of looking quizzically at the strings on the racket when I miss a shot but still manage to hit myself instead of the ball every now and again.
Occasionally, just occasionally, I feel like I'm making Mosh run around after the ball rather than the other way around. I hope that is the case.
