Difficult Socializing

I wonder has anyone noticed how difficult socializing is for some high school students? When we are at school we are mostly studying, if you are an athlete we have practice and afterward we are to tired to do anything. So the only time we can really just socialize is on the weekends, which for some people is this a difficult task because we are busy with events and things. So what helps the students make time to socialize or hang out with there friends???
