Clarification

It was the the cheapest store for food I'd found since moving here. For all the previous fifty-cent packets of crackers and two-liter bottles of pop, she'd never spoken to me before.

-So where've you been?
-Sorry?
-You haven't been in for a while. I haven't seen you.

Before leaving the store clutching my one-dollar packet of Corn Flakes and my receipt I explained:
-Oh, I've been lying low.
And then added for clarification
-I haven't been eating food.
