David Simmons is the son of Joseph Simmons
Background[]
When David was seven, Joseph bought him a bicycle, a fact Joseph still likes to bring up in arguments. When David was an adult, his mother died, and Joseph moved in with him. The two didn't get along, so Joseph moved to the retirement center. David still visits him every Thursday.
On the series[]
David finds out that Joseph plans to marry Eva Martin. David is adamantly opposed to it because he thinks Joseph and Eva are too old to get married, and because he thinks Joseph has forgotten David's mother. Joseph and Eva get married anyway. David arrives during the ceremony, which is being held at the Keaton family's house. He apologizes for his earlier behavior, says that his mother would want Joseph to be happy, and congratulates Joseph on his marriage. Joseph makes David his best man.
