Answer for question 4184.

[Error: unknown template qotd]Cutting my hair. I can trim the front and trim the back and even feather it out on top after a fashion, and make it do four months or so between 'proper' cuts -- but it's such a beastly job fiddling round trying to see the reflection of the back of your own head and stopping the little bits from going down your collar (I tend to do it in pyjamas and then send the pyjama jacket to the wash) that increasingly often I just go to get it cut again when it first starts to get long.
