Parties are great because you get to meet and speak with so many people; but one of the biggest downsides to a party can be those same people.
You know the ones: the stereotypes you can't help but run into at functions.
Maybe you know someone who fits the role of the emotional wreck or the "I have work in the morning" guy--or maybe you've been the party stereotype yourself.
Either way, it's okay. Parties are great opportunities to socialize and if you want to navigate your next party with ease, learn how to identify the different people at parties so you know how to interact with them successfully.
