Rhinotillexomania - nose picking

I am busy picking my nose in a precious moment of privacy, when he bursts into the bathroom to use the facilities, “ooo what you are do?”
I put down the tweezers to explain myself, “well I’m pulling off all the dead sunburnt skin from the tip of my nose.”
“Rudolph!”
“Yes……thank you. It’s very sore actually.”
“Why it burn?”
“The sun……when we were in England.”
“It is being polite?”
“Polite?”
“Er…….English style nose pickin.”
“!”
