She uses the barstool to help get herself back on her feet. She quickly smooths out her hair and then her shirt. "I-I didn't have that much to drink."
Maybe she'd forgotten how much she'd downed. "Right?"
She hesitates before continuing. "My daughter went missing and so... I-I can't sleep and I find myself in bars. I'm sure you hear about these stories all the time."
She was a talkative drunk.
