Yeah. Way easier than it seems. Used to cut my brothers hair years ago too. That stopped though when his ear got in the way of my scissors one day.
Depends on how they've done it and if I like it or not. I'm also more likely to tip if they're not miserable ****s and are quite chatty.
Nah usually 5 on top, 3 on back and sides. Takes about 30 minutes. I've ****ed it up a couple of times and ended up with one all over though.
Yeah that must be quite awkward on yourself. I'm imagining he looks a right **** and everyone is just playing a practical joke on him by not telling him for a decade.
Hardest bit but the difference between 3 and 5 isn't much. Sides aren't too bad but the back is a pain.
