My W does that kind of thing more frequently. Stress does that. Focusing on oneself does that. MLC definitely does that. Good thing you are able to just shrug it off. Don't ding her for it. Obviously, you will probably have to bring it up, but I'd do it with a light-hearted, "I'm glad I'm not the only one who does that kind of thing."
