I hate that soccer players don't celebrate with their team after a goal. Anyone else notice this?

I'm just getting into soccer, but it absolutely kills me when after a goal, the player always tries to get away from his teammates and go solo. Maybe I haven't watched enough soccer, but I've seen hundreds of goals and this happens everytime. I'm like, hug your teammate damnit! Last time I checked it was a team game!!! By the way, I'm very stoked about the World Cup coming up in June, but I just wanted to ask you diehard soccer fans what was up with the "going solo" thing after a goal.
