					There is a social contract in the family, 
- 
				  
					and in fact when you grow up-- when you are not a small child anymore-- 
- 
				  
					then you will realize how much of a contract it is. 
- 
				  
					Eventually--I hope there is nobody in this room, 
- 
				  
					but I suspect there are probably a very 
- 
				  
					few who at one point thought enough was enough; 
- 
				  
					you know, my mother and father is really a pain, 
- 
				  
					and therefore I don't want to do much with them-- 
- 
				  
					will break the contract, right? 
- 
				  
					It does happen to some people in their life. 
- 
				  
					As a father, I hope it would never happen, 
- 
				  
					but unfortunately it occasionally does.
