Inhale. Hold. Exhale. Inhale. Hold. Exhale. Let the thick smoke cool before you take it into your lungs. Repeat until everything goes away...
Or until you're too dizzy to stand. Something someone says reminds you of something you tried to forget, so you pretend to be enthusiastic about the drinking games. You pour your shots a little higher than everyone else's. Repeat until everything goes away...
Or until you're trying to ***** silently. Tell them it's food poisoning. They know it's not. Watch their eyebrows curve with pity and concern. Don't tell them you're trying to disappear. Repeat until everything goes away.
