Tell Me A Riddle Puns

Today my father asked me:

F: "Someone's mother.."

Me: "Oh no, please no" (In mind)

F (continues) : "... has four kids: west, south, and north. What is the name of the fourth kid? Tell me"

Me: "..." (Is he making fun of the riddle or himself)

F: "And let me tell you the answer is not EAST, haha"

Me: "..."

F: "It isn't easy eh?"

Me: "Kill me god, please just kill me. This is so painful"

DEAR NEIGHBOUR: Hi, Fred, this is Richard, next door. I've got a confession to make. I've been riddled with guilt for a few months & have been trying to get up the courage to tell you face-to-face. At least I'm telling you in this text, & I can't live with myself a minute longer without your knowing about this. The truth is that, when you're not around, I've been sharing your wife, day & night. In fact, probably much more than you.
I haven't been getting it at home recently, & I know that that's no excuse. The temptation was just too great. I can't live with the guilt & hope you'll accept my sincere apology & forgive me. Please suggest a fee for usage, & I'll pay you. Regards, Richard

NEIGHBOUR'S RESPONSE: Fred, feeling very angry & betrayed, grabbed his gun, went next door, & shot Richard, killing him. He went back home, shot his wife, poured himself a stiff drink & sat down on the sofa and calmed down. Fred then looked at his phone & discovered a 2nd text message from Richard.

2ND TEXT MESSAGE: Hi, Fred.
Richard here again. Sorry about the typo on my last text. I expect you figured it out & noticed that the darned Auto-Correct had changed "wi-fi" to "wife".
Technology, huh? It'll be the death of us all.
