You almost certainly haven't given your mother the full picture. In our culture, with its hostility towards men who wear hair, the only men who go to the lengths of getting themselves fitted with a hairpiece are those for whom hairloss has been a seriously painful experience. It's not a mere act of vanity like getting your teeth whitened (which is how your mother is looking at it), but a cure for a debilitating condition.

But this is an unspoken truth except in places like this. It's impossible to explain this to anyone who hasn't suffered it, and probably best not to try. No man could discuss this stuff with his mother. Interesting that your dad gets it though.
