The context of the following conversation is Casey was with her friends and was trying to impress them, so she tossed her drink back.:
Casey says I have such a headache today..
The friend responds Did you go to a party or something?.
Casey responds No, just to a bar with some friends. But I normally don't drink and last night I was doing shots..
The friend responds Why would you do shots if you don't drink? That sounds kind of risky..
Casey responds I don't know. I guess I wanted to impress everyone and look more fun than I am. I tossed back quite a few whiskeys..
The friend responds Well drink lots of water today. You're probably dehydrated..
