For those of you who have a step-mother/step-mother-in-law

Do you send her a Mother's Day card?

I don't know what to do about Step-Mother-in-Law. If I were to ask DH if we should send her a Mother's Day card he'd say, 'helllll no', but I know that she'd really like to get a card.
She and I are not really that close (she and FIL live in Alabama) and DH is definately not close with her. He doesn't dislike her, he just doesn't really have any feelings towards her at all.

So I don't know if I should listen to DH and NOT send her a card (risking hurting her feelings) or send her a card even though DH and I don't really have any sort of bond with her.
