When I was in primary school I liked to pull at the bra straps of female classmates, then release them with a 'piak' sound. They enjoyed it. Some girls are early bloomers during puberty, start growing breasts and wearing bras in Primary 5 or 6.
One of the girls also kept asking me to guess which brand of bra she was wearing. Her favourite brand was Bee Dees, I checked.
So fun. Kids these days are missing out.
