I often have difficulty parsing speech in noisy bar/club environs. This has always made me into a bit of a wallflower. Then I started dating a woman who was also very wallflowery, but mostly because it was a lot of effort for her to talk loudly.

We ended up having a lot of arguments, because she'd say things to me, I'd tell her I couldn't understand what she was saying, then she'd refuse to talk louder but still hold me accountable for remembering what she said.
