I didn't know it was snack time.
A dumb excuse to skip eating when you're too busy pretending you're not hungry
'I didn't know it was snack time' when I was pretending I wasn't hungry and ignored the snack
'I didn't know it was snack time' while I was busy talking to my friend and didn't notice the snack
'I didn't know it was snack time' when I was too busy being cool to eat
