I know it's fashionable but don't put your small son in wide legged boxers on school days.I met two little girls giggling uproariously in the corner of the corridor. They were watching a PE lesson in the hall.
"What's all this noise, what are you laughing about?" I asked.
Serious amounts of snorting and gasping and then one said,
"Look, look Miss, they're going to do it again!" Followed by squeals of laughter and "Josh's is the tiniest!"
So I looked and the children were lying on the floor making star shapes. . .
As I said, don't put your little boys in wide legged boxers, it's untidy!
