I'm planning to return home for a week or so at the end of August. I intended to come sooner, but didn't quite figure out the details of that sensibly in advance.
The planned visit is, obviously, primarily for the delight of seeing family and friends, followed by the relief and joy of interacting in shops and restaurants with less confusion, eating entirely recognisable things in a fully equipped kitchen, and being able to go to the toilet in a house without having to first swing my sink into the shower. Nevertheless, it's not quite irrelevant that I need to arrange regular trips back home in order to avoid a regression back to the fateful 'long-haired months' of 2006/07.
I really don't want to go somewhere here to get my hair cut. I try to avoid situations in which I might need to talk too much to strangers without any clear idea of the outcome, or explain anything more complex than could be expressed by pointing and grunting if absolutely necessary. I've only just recently managed to pluck up the courage to ask for bread rolls ('Brötchen') in bakeries, partly because I've been told foreigners pronounce it amusingly (we do) and partly because there is a risk of follow-up questions*. Nevertheless, shops generally aren't the worst. It is comforting to know that, if the required interactions go badly, at least I can leave a shop fairly quickly. What I don't want is to know that, instead, I will have to stay seated, replaying the foolishness in my mind while caped like a superhero whose only power is linguistic incompetence, as a stranger touches my head.
But, realising that the trip won't be for some weeks, and inspired by the unexpected support of my mum (a sure sign that my hair must have been getting pretty unruly), I finally mustered the courage to implement the emergency plan of shaving my head myself.

It was arguably the most difficult thing I have ever attempted. Arms do not contort enough, eyes cannot see far enough, two mirrors cannot be arranged well enough to make this really possible**. It was early the next day before I was finally able to stand triumphantly in my hair-lined flat, and even then uncertainty was a more dominant emotion.
I don't know for sure whether it worked. My mum was able to offer vital advice and diagnoses through video-conferencing at important stages, and in the end she said that she thought it had gone all right. But I knew that it was somewhat like an expert trying to judge the severity of an oil spill from BP's grainy footage. It wasn't quite the same as seeing it in person. So now I need to wait until Monday, and hope that my colleague's honest side will overcome his mischievous side when I solicit his opinion.
*-I'm getting better though. Last week I asked for sunflower-seed bread, which is 'Sonnenblumenkernbrötchen'. Yes. One word. 'Sonnenblumenkernbrötchen'.
**-I realised later it might have been better to try it in
Cafe Extra Blatt. Here, if you choose the right (or, if you're paranoid, wrong) seat, there are enough mirrors around that I once calculated you can see yourself from approximately 10 different angles just by moving your head slightly - thereby making it the ideal cafe for the self-obsessed cubist.
