Loosen Up, Lighten Up Day

I had no clue that this was Loosen Up, Lighten Up Day partially because I didnt know such a thing existed.  I thought it was quite Ironic because it is a Monday and usually Mondays are horrible! Today is not though, it has been a very good Monday ( knock on wood), not much homework at all, which is always a plus. I seriously wonder what this day is all about, is it to not let anything bother you? Take everything everyone says lightly? I dont know what it is but, it seems to be working on this November 14th!
