Did you know a synonym of mirth is GLEE? It's one of my favorite words!
Glee goes along with giddy, another one of my favorite words!
Ok, so why am I giddy today? Because someone was nice enough to think of me and is giving me little teeny baby clothes for my daughter. I've got bigger sizes but nothing little because I didn't want to get my hopes up that she was going to be very young. The thought of little 6 month clothes makes me giddy. Fills me with glee! It makes me mirth-ful? (Ok I know that was a stretch).
