Q: Just now, at 9:35 PM, a small head of a unit called me. I was taking a shower and didn't notice. Should I call back?

A: Don't call back, it's 100% bad news. Because after 9 PM, normal people know not to call others. At this time, if the unit calls you,

one is that there is a problem with the unit. For example, a water pipe burst at the unit, and they need you to rush to repair it.

Two is that they have a problem themselves. They were caught in a red romance and need to find someone to bail them out. Not receiving the call is a good sign.

If you are really curious, you can call your colleague sitting across from your desk and ask if they want to take the kids to play football after work tomorrow. If there really is a major issue at the unit, the other party will inform you.

If the small head asks you tomorrow (which generally they won't), just say you went to bed early last night and missed the call.
