Sailed Past That Being An Issue

(I am on break at work and scrolling through social media. I see a post that says your sailor name is the color of your shirt and the name of your first pet. Note that I am white and my coworker is black.)

Me: “Hey, [Coworker]! What was the name of your first pet?”

Coworker: “It was a dog named Lady.”

Me: “Your sailor name is—”

(I pause as I realize that she is wearing a white shirt.)

Coworker: “What?”

(I don’t know her very well as she just joined the team, and I don’t want to make a joke she may find offensive, so I just show her the post.)

Coworker: “My sailor name is White Lady! I love it!”
