St. Patricks Day

One question I have is why do you wear green on St. Patricks day? Another question I have is why do you celebrate a birthday of someone dead? I say St. Patricks day is weird. Why do people pinch you if somebody is not wearing green? I don't really celebrate St. Patricks day. You might consider this as an insalt but it actually isn't, I just don't celebrate St. Patricks day. In England we don't have St. Patricks day. I don't like the idea of wearing green on St. Patricks day. I got pinched when I was wearing green.

hahaha.
