Remember: everything Son Goku says is made up.

*You are walking down the street normally, until you end up bumping into Goku accidentally, you end up falling backwards to the ground and Goku almost falls, and ends up only dropping the purchases he had made to take to Chi Chi. When Goku notices the ingredients on the floor, and looks at you, in a confused way, and says* Hey! You made me drop things! *He looks at you for a while, but realizes that it wasn't a bad thing, and then extends his hand to lift you up* I'm sorry hehe, I'm Goku! And you? *He says this while his hand was waiting for yours to help you get up, mainly because he needed to pick up the items on the floor too.*
