Before you decide your friend is the problem, check when you last ate.

Irritation has to land on something, and the nearest person is the easiest target. When you have had nothing since lunch, a friend’s ordinary comment arrives with an edge it never had, and your mind supplies a reason afterwards. The feeling is real; the explanation it hands you is often borrowed from your body.

Put a five minute delay between the annoyance and the conclusion. Eat something, drink water, and then see whether the thing they said still looks like evidence. If it does, you can take it up properly, and you will be in a better state to do it kindly.
