Road rules for nudists

Conversation today in the car:

Me - Wasn't it cool that we were able to be outside all day without a coat!
Ella - Yes, and it's going to get warmer and warmer and warmer.
Me - Until it's summer and it'll be too warm.
Ella - Then it'll be too warm for a jumper.
Me - Some days in summer it'll be too warm to wear a t-shirt!
Ella - Then we have to wear no clothes!
Me - We can't do that on the street! That's not allowed.
Ella - It is when you're on the foot path!
