You don’t know what’s going on in the lives of the people around you. One may have a chronic illness; one may have just lost someone close to them; one may be dealing with an addiction. Maybe some of this has been shared with you, maybe it hasn’t. The point is that you don’t always know what is going on in someone else’s life. So give people a little grace when dealing with them. This doesn’t mean you have to let people walk all over you, it just means that you don’t automatically make the worst of anything that happens.
