A man received the following text from his neighbour:

I am so sorry Bob. I've been riddled with guilt and I have to confess. I have been tapping your wife all the time. I'm not getting any at my house, but that's no excuse. I can no longer live with the guilt and I hope you will accept my sincerest apology, along with my promise that it won't happen again.

The man, feeling anguished and betrayed, went into his bedroom, grabbed his gun and without a word, shot his wife and killed her.

A few moments later, a second text message came in: Damn spell-check. I meant "wifi", not "wife".
