Watch out for your friends.
Go
to parties with friends you trust, always have a designated sober
friend, and help someone when you think their safety is compromised.
Say you're at a party and you see an extremely intoxicated girl being
led upstairs by a guy - what should you do? If the situation doesn't
seem right, speak up. You don't have to be confrontational, but
neutrally interrupting a potentially dangerous situation can allow you
to scope out the danger and offer help.
