How Mentally Strong People Respond to Snarky Comments. https://www.psychologytoday.com/blog/what-mentally-strong-people-dont-do/201709/how-mentally-strong-people-respond-snarky-comments
Mentally strong people understand when to be assertive and they’re not afraid to speak up. But they also recognize that it’s sometimes best to ignore someone who is using snarky comments just to get attention.
They don’t feel like they have to get the last word in and they aren’t interested in arguing just for the sake of it. But they aren’t afraid to call someone out for their behavior.
Commit to using direct communication. When it’s warranted say something like, “I noticed you rolled your eyes when you reminded me about that project. Are you upset about something?”
Or, if you’re in a meeting and someone offers a snarky comment about your latest idea, turn and talk to the people who seem genuinely interested. Then, you’ll be putting your attention where it should be—with positive people.
