Nothing to worry about, lad. Everyone's edit function has gone down the drainpipes lately, as it is.
I did have some interesting developments, pop up. So if you don't mind helping out with some minor welding and number crunching, if your mum doesn't mind possible explosions outside of her home, and if your girlfriend doesn't mind too terribly much that a smidgen of your free time might be gnawed on? Maybe you wouldn't mind helping out, a day or two, a week. Or an hour here and there.
Provided the remainder of your studies don't go down the drainpipes, either. Because naturally, all of that mess needs dealt with as the highest priority.
