Merry Valentine's Birthday!

The setting in my Grandma's living room is a confused and somewhat cluttered one. From just looking at it, and outsider wouldn't be able to tell whether it's Christmas, Valentine's Day, or someone's birthday. It's March, but the Christmas tree is still standing tall and full of decorations. The garland is silver, but instead of traditional Christmas ornaments, there are Cupid and heart cut-outs hanging from the branches; the kind of decorations that you would usually see hanging from doorways or ceilings on the appropriate holiday. To add to the confusion, there are gifts for my Grandma under and around the tree. They've all been opened, but the different cards read "Merry Christmas" and "Happy Birthday".
