Three times this school year, we've chatted amiably at pick-up time. And three times now, a third mom has approached us. Each time, in mid-conversation you've turned your back to me to talk with the third party (different person every time), and ignored me for the duration.
I know that Hanlon's Razor states that one should:
Never attribute to malice that which is adequately explained by stupidity*.
* or in this case lack of manners.
But it's starting to feel personal. Ya know?
Cut it out.
