How do you act around grumpy people?

When I'm around grumpy people, I try to remain calm and positive, as their mood can be contagious. I might engage them with a friendly gesture or a light-hearted comment to lighten the atmosphere. If they seem open to it, I offer a listening ear, showing empathy without pushing them to share more than they want. Ultimately, I respect their space and adjust my approach based on their reactions.
