QUESTION #5: Do you have any suggestions for people who want to try using furniture for the first time?
ANSWER #5: Furniture is fun to play with, like Tetris. Playing Tetris is good practice for using furniture. Thank goodness for video games! Before you begin using furniture, go play Tetris for several hours or better yet, go play for a few days, or even better than that, play Tetris for a full week. If you don’t have Tetris, then another great way to prepare is to rearrange all of the furniture in your house or apartment, or reorganize your garage. After you finish spring cleaning, using furniture to lock up type will seem like a piece of cake! Cake. Are we done yet? Let’s go get some cake.

Cool. I do enjoy that puzzle-mania one can practice with furniture; I think my long-ago forays into that realm still strongly influence my play with cut-and-paste in Photoshop (etc) nowadays.
All the world is a puzzle, figuratively and literally. Happy puzzling!
Now I’m thinking about cake. And Tetris. Shoot.
It sounds like you are going to have a fun day!
Good point!
