Is apologising gendered?

Occasionally the idea for a blog doesn't so much suggest itself as smack me in the face and insist that I write it. This is one such occasion.

This was prompted by three separate incidents in fairly short order. I was on the receiving end of suboptimal behaviour from three different people, and on none of these occasions did the person apologise. I say “people” when what I actually mean is “men”, and it gave me pause to wonder whether the propensity to apologise, or not, is gendered. I had a suspicion that it was, and this prompted me to look into it further.
