Learning a few about daily life today

I am a geek ... ok, nerd. So a lot of stuff that other regular people take for granted, I actually have to learn. In fact I learned a few things today:

• Walmart closes at 10 pm on Sunday. This is awesome before most of the other stores close at 6 pm on Sunday.
• My bed is in Full Size. I learned that there are 4 kinds of bed size: twin, full, queen, king.
• In a Fitted sheet set, there are multiple item, and all I really need is the Fitted Sheet. I brought a complete set which also included cover for pillow and a flat sheet, which were something I didn't want. I returned the set and brought just the Fitted Sheet.
• Walmart's return policy is awesome. People, please don't abuse it.
