haircuts
You hair has been freshly cut, your back is to the mirror, the barber/stylist then styles your hair and spins you around. You examine the work. And no matter how good or bad it looks, don't you get a sinking feeling, a feeling of finality, like, "Well, this is it...this is as good as it is going to look, because a professional styled it. No chance of topping this until maybe the next haircut."
