Today was no different, up to that point. After a reminder to say "Thank you", this conversation followed:
J, M, and A: ¡Gracias!
Me (quietly): In English, please.
J and A: Thank you!
Checker: You're welcome.
M: Shucran! (Arabic)
Me (still quietly, but with a LOOK): IN ENGLISH.
M: (only slightly subdued) Thank you.
Checker (after a brief pause): Was that German?
Me: No, first Spanish, then Arabic.
Checker: Oh. (Longer pause) Do you homeschool?
Sigh. Don't other people's six-year-olds pick up Arabic words and phrases from their dads?!?
Yes, we homeschool!
