how tall are you?

this can be found in most train stations for kids to measure how tall they are to see if they need to pay fare. I remember when I was little (around 4-5 yrs old), sometimes my grandpa will carry me before boarding the bus so that I dont have to pay bus fare.

and I also remember I used to love measuring my height! i get really thrilled when my height has increased from the previous height measurement! and coincidentally the conversation topic at lunch today was about heights!
