(For a long time = A long time ago)
On our way to the supermarket. R and L are playing at lifting each other.
L: Let me carry you now.
L: Uhhhh, you’re too heavy for me.
R: You can’t because usually boys are stronger than girls, ’cause for a long time they used to do fishing.
What’s THAT about? Do you mean because men used to be hunters?
L: And the womans for a long time used to pick strawberries.
Me: Oh yeah, and women would gather fruits and nuts for everyone to eat.
R: But papa only used to goed to the supermarket.
All of us: Hahahahaha.
L: And mama also goed to the supermarket to buy food!
