drunk dissolution

A bar. 2 friends. One is polishing of what looks like her 3rd or 4th drink. A sudden lull in the conversation before lights up.

1: (taking a deep breath after she gulps her drink) --whoa. i haven’t drank this much in a long time.
2: drunk.
1: i’m not drunk.
2: no. you haven’t drunk this much in a long time.
1: yeah. (takes a deep breath and says on the exhale--) i know.
you know what i noticed? or heard, rather? or read?--i forget. whatever.

2: its
1: it’s what?

1: are you mad at me?
2: what?
1: are you mad at me?
2: (laughing) what are you even talking about? here. have some water.
1: stop yelling at me.
(silence. uncomfortable shifts in respective seats. silence.)
2: (just making conversation) i wish it would stop raining.
(silence)
1: it’s always raining somewhere.
(1 suddenly downs the rest of her drink and rises to leave.
2 is left to contemplate the sudden truth she is faced with.)
