A) Leaves out a comma before Walt (i.e. this weekend, Walt?)
B) Is not a direct sentence. The speaker is not talking to Abraham Lincoln; she/he is only talking about him.
C) Uses the comma correctly in a direct address. The speaker is saying something directly to Denise and there is a comma directly after her name.
D) Again, the speaker may not be talking directly to the boys but simply to the parents of said boys.
