Our boys like to play together, but sometimes the distance between 2.5 and 5 yrs is just too much.
Ben called to Charlie to ask him to come and play a game in the other room. Charlie raced out to join in calling "Going to play with Ben" on the way out. Then we heard a long description of the rules of the game from Ben. There was a brief pause and Charlie was back in with us saying "Can't play with Ben". I asked "Too hard?" and Charlie said "Too hard."
