Can you replace the question mark with a number?

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, and has a long drawn out fight with his wife about her infidelity.
A few moments later, a second text came in:
Correction: I meant "wifi", not "wife".
