Agreed. You don't need to to home to change. It's one day, it won't kill you. I used to go to school in pajamas on days where I didn't feel like getting dressed. It's not that unusual.

How was that obviously a joke? Some schools have a pj day.

Not if the school doesn't say so over the PA system. Plus, that is more in celebration of Homecoming and stuff like that. I wish I had known better though.

We would have pj day whenever. The fuck is homecoming? Where was everyone?

They were at your mom's house, 23.

Same with my high school. Homecoming is celebrating the first football game of the season. The school usually has a dance later on.

So why is it called homecoming?

It's called homecoming because it is the first home game of the season.

OP is from the UK though, and as far as I know every schoolkid between Year 1 and Year 11 has to wear a school uniform. It's not customary to even wear your own clothes to school here (barring non uniform days) let alone pyjamas. I'm honestly surprised OP wasn't sent home to change, my school sent people home for wearing trousers the wrong shade of grey!

The most logical thing to do.

something tells me that OP wasn't comfortable in the slightest :D
