I think most of these holidays are way too hyped. My DD shows me how much she loves me everyday and I know how much my DH appreciates all I do for our family. I don't need expensive gifts and flowers on the 2nd Sunday in May to tell me that. I also let my own mom know how much I love and appreciate her all the time. Luckily she isn't hung up on the day either.
I'll have to let my mother know she's not crazy by keeping them there. She talks to them sometimes.
