I like it, but we don't get involved in the commercial stuff.
Start with the Church service at Salvation Army (one of the 3 times a year we go ) There is an opportunity to put a daffodil in a vase for any mums not present, for whatever reason. We'll invite my Mum & Dad too and all ladies there get given a little bunch of daffs by the children, then tea and cakes after. All very friendly and almost "quaint" TBH.
We will not be going anywhere near a restaurant. I will buy my Mum a card, but she has never had a Mother's Day present and would think it was a horrible waste of money. DS's will poss make something for Grandma. DH has been under strict instructions since before DC's were born never to let DC's spend any money on any trinket that has Mum/Mummy on it.
If I'm really lucky, I might get breakfast made for me and to go out for a nice family walk.
