The context of the following conversation is Kendall could buy one of the toys with the money they had and share with their brother.:
Kendall says I hate that I have to share my toy with my brother..
The friend responds Well everyone has to share with their sibling..
Kendall responds Yeah, but I bought the toy with my own money!.
The friend responds Don't be selfish, Kendall..
Kendall responds It's just not fair. If Tommy wants to play with a toy, he can buy it himself..
The friend responds But Kendall, Tommy is too little to be making his own money right now..
