Relationships are like a freeway. Freeways have exits, so do relationships. The first one, my personal favorite, is 6 hrs in. You meet, you talk, you have sex, you leave while she's in the shower. The next exits are 4 days, 3 weeks, 7 months, then a year and a half, 18 years, and the last exit, death. Which, if you've been with the same woman all your life, it's like 'are we there yet'?
