I hate this about me, but I find that I actually ACT differently if I forget my makeup! How sad is that?? Really - I think I act like someone who wants to blend in with the walls - very little eye contact, and no joking around and lingering with anyone - male or female - if I don't feel like I have my best look going on:

On a mostly daily basis, I put on concealer (Covergirl 3 in1), then blush, then lip liner, lipstick and perhaps some mascara, if I'm not running late. I'm mostly about the concealer and the lips, though. And funny enough, my lipstick HAS to be nude - no reds, pinks or oranges -- so why so weird about whether I'm wearing it or not?? Go figure...
