Oh oh... (bit naughty)

A man received the following text from his neighbor:

I am so sorry Bob. I've been riddled with guilt and I have to confess. I have been tapping your wife, day and night when you're not around. In fact, more than you. I'm not getting any at home, but that's no excuse. I can no longer live with the guilt and I hope you will accept my sincerest apology with my promise that it won't happen again.

The man, 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 came in:

Spoiler:

bloody predictive text. I meant "wifi", not "wife".
