Guys care about sports teams. I'm not talking about simply rooting; I'm talking about a relationship that guys develop, a commitment to a sport team that guys take way more seriously than, for example, wedding vows.
'I'm sorry,' guys are always telling women, 'but I'm just not ready to make a commitment.' Guys are in a permanent state of nonreadiness. If guys were turkey breasts, you could put them in a 350-degree oven on July Fourth, and they still wouldn't be done in time for Thanksgiving.
