nostalgia hits in mysterious ways

Like wdym, if the wind hits my face in a funny way I'll suddenly be 11 again walking to the Christmas parade ith my Tia?

Wdym if I'm listening to the right type of music, in the right room, in the right season, I'll be 9 years old writing letters to all my classmates to my birthday party that nobody came to?

Wdym if I smell something a little off I'll be 5 years old sleeping on an inflatable mattress and watching Willy Wonka the night we moved into our new house?
