Extroverts gain energy(energy not in the literal sense,more like mental energy) from social situations whereas Introverts loose energy(Again,more like mental energy) in social situations.
If you get happy after an outing with your buddies or a party you're probably an extrovert whereas if you get mentally exhausted and tired after a social event and goes to your house and sits alone somewhere to "recharge" you're probably an introvert.
