The end result was this:
It seemed super nerdy to me at the time, but it looks almost like the exact haircut I'm trying to get my hairdresser to give me now (I think it's called an 'ivy league').
A few weeks later, and I was once again in need of a haircut. Not trusting that I would again encounter the ease of my first haircut, I avoided finding a barbershop, and on a strange whim bought a tiny pair of scissors at a stationary store in Aqaba. I cut it that night in my hotel room, with little help from mirrors or much of an idea of what I was doing.
This was the result, which I have to say I don't totally hate:
The back, however, looked like this:
Like I had alopecia or something.
Despite this obvious drawback, I pretty much continued cutting my own hair for the subsequent four years (though I eventually purchased a pair of clippers to make it an easier job).
