A six-year-old kid is shopping for a new school uniform with his mum. His mum gets him to try on a grey V-neck sweater. "How do you like that?" she asks. "Is it comfortable? Not too itchy?"
"Mum, you're not buying me one like this! My teacher sometimes wears one like it, and when she bends over I can see her lungs."
