Rein in your anger horses:: I'm not saying that us ladies need makeup; we definitely don't. What I am saying is that, based on my experience and the experience of several ladies I've talked to, men often don't think we're wearing makeup when we are. That's because for many ladies, the point of makeup is to look natural, not like Tammy Faye or this dumb eyeshadow thief. So, when dudes tell us to go without makeup, they might not know what they're getting into.
