I'm not a fan of Mothers Day. I don't need or want one "special" day to be shown how loved/appreciated I am - I expect that on a regular basis!
MIL, on the other hand, expects a bouquet of flowers delivered to her door on the day. We live 3 hours away and can't visit then so it usually costs about £50 for (judging by the photos MIL sends) a rather mediocre display of flowers.
WIBU to suggest DH sends her a £20 M&S voucher and asks her to treat herself?
