I tend to diverge from a recipe, and a prime example is when I thought I'd make a tofu scramble using my homemade tempeh. Tempeh, though, is not so moist as tofu, so I thought I'd add a tomato or two for the moisture... and then I ended up not following the recipe much at all — but it was very tasty. I made a kind of spinach-&-tempeh stew.
When I've slept on a bed without a headboard, my pillow tends to fall off the end of the mattress as I push it around when I sleep. The headboard acts as a fence to keep the pillow on the bed. To me, a mattress sitting on a box spring held up by a frame doesn't look so much cheap as incomplete. But since the bed is typically out of sight in a bedroom, people generally don't sit around gazing at it.
