People who brag about what they do not do annoy me. These types brag that they do not bathe after 11 a.m., or they do not eat potatoes, or they do not drink alcohol or tea or coffee, or they do not use hair brushes, only combs. The may sit in a living room spreading their oily hair and combing out falling strands all over the floor, but they proudly refrain from using a brush.
Reasons for what they do not do may arise from religious or other traditions, or from thin air, or from superstition or from sheer nonsense. Whatever the reasons for not doing stuff, not doing something is nothing to show off about. I personally don’t like walking under ladders or crossing black cats because I am superstitious. But I know this is ridiculous. Someone dear to me is repelled by bananas, but then again she does not act as if banana avoidance is a virtue.
Let’s brag about accomplishments, keep our bragging low key, or even better, let’s not brag. But that is difficult. Years ago a respected elder suggested that it was okay to brag about non-professional achievements, though I do not understand why. Still it is important not to brag about not bragging.
