National Month For ????

I honestly don't know why people would set up unusual things for us to celebrate each other. I find it weird but I guess it's what people thought would be interesting to do. I believe that some people do celebrate these things. I really didn't know this month was for smiles. Three other things we should celebrate in May is be yourself. Also a relaxation day and don't wear make up day. I'm not sure what I would really like to celebrate this month to be honest.
