Was It Something I Said?

Dear Mom At School:

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.

Yours,
M.
