My parents had a neighborhood grocery store when I was a kid. Our house only had a single bathroom, so often, I’d be getting ready for school at the same time she was getting ready to go into work, and we’d both be in the bathroom. I’d finish my shower, and be wrapping up in my towel behind the curtain, while she’d be doing her hair in the mirror, having imaginary arguments with “bitchy customers.” - At least that was her answer when I finally asked her what the deal was with her arguing into the mirror in the morning.
