Overview
A friend or coworker you especially like is dealing with some heavy stuff right now, and you need to make exceptions for some of their potentially odd behavior. You might not be sure why things are happening the way they are happening with them, but you don't really need to. All you need to do is to let this person know you are concerned, and give them time to work things out on their own. More than anything else, they need your patience and your support right now.
