My beautiful bride of 36+ years is a retired barber. BARBER, not a beautician, as she would correct people who called her that. So, on the plus side, I get frequent, regular haircuts at my own convenience, for free. And every single haircut has been perfect. HOWEVER, on the negative side, for a half hour every two or three weeks, I am a captive audience to someone with very close personal knowledge of me and all my flaws and past mistakes, whom, depending on timing and luck, may or may not have one or many personal grievances with me, and is holding a very sharp instrument with which she possesses considerable skills. In certain circumstances, I can be a somewhat fidgety, nervous customer, as you can imagine.
But the haircuts themselves have always been perfect.
