Ross and Rachel, Friends: Ross and Rachel taught us one glaring fact about love: that it's hard. It seemed like these two were always missing each other — one was feeling it when the other wasn't, one was with someone else while the other was pining away for them, and then there was that whole "we were on a break" debacle. But through it all, they maintained an amazing friendship and eventually went on to build a family with their daughter and, as implied in the finale, a future together. All of this was done with a lot (like, a lot) of hard work and time. So we learned not to have any delusions about a storybook romance, because we didn't get to fast-forward through the middle to see just the happy ending with these two. We saw the good, the bad, and the ugly.
