How to reply to her pet peeve about loud chewing on Hinge

People don't list random pet peeves. She chose loud chewing because she actually encounters it regularly and it actually bothers her. That means she's someone who notices things, has standards for how people behave in shared spaces, and probably finds it funny that she's particular about it.

This is not a sign she has anger issues or is difficult. It's a sign she's observant and has a sense of humor about small annoyances. She's inviting someone in on her perspective by naming something specific instead of being vague about wanting someone 'respectful' or 'considerate.'

Your opener should land somewhere between completely ignoring what she said and making it the whole joke. Pick a detail from her prompt or profile that lets you add something of your own, or reference a related observation you actually have.

The move is to treat her as someone who thinks about things and notices the world around her, then show that you do too. You don't have to agree with her about chewing. You could talk about a different small thing that drives you up the wall, something about table manners or shared spaces, or even turn it into a quick question about what else bothers her. The point is you're engaging with her as someone who has opinions, not just reacting to the topic.

The window matters here because if you wait too long, she assumes you were browsing without real interest. Send your reply while you're actually on the app and thinking about what she wrote. That timing also means she's more likely to still be using it and to respond.

If she doesn't reply after three days, let it go. No follow-up, no "did you see my message." If the first reply doesn't land, a second message just looks like you're trying to convince her. Move on and focus on replies that get responses.
