Not exactly something I can't do without, but I much prefer to use teaspoons when eating anything that would normally be eaten with a tablespoon. I eat soup with soup spoons though, that'd be a nightmare with a teaspoon. Also, I use a knife in my left hand and fork in my right despite being right-handed.
who in their right mind would eat plain mayo anywaysI licked a bit off my finger when I was making tuna salad. It's not bad, but it's kind of next to margarine on things you probably shouldn't eat on its own.
