People should not have to decode your mood before bringing you a problem.

Unpredictable weather at the top of a group changes what reaches you. If people have to read your face before deciding whether today is safe, they will start choosing their moments, which means bad news arrives late and small problems arrive large. None of that requires you to be unkind; variability is enough, because the cost of guessing wrong falls on them. Steadiness is less about temperament than about being the same person to approach on a bad day as on a good one.

Notice whether people wait for the right moment with you. Ask them to bring things immediately and prove it by how you respond the next times.
