A man received a message from his neighbour...
Sorry that I have been using your wife...
I have been using day and night...
I use whenever you are not at home...
In fact, I have been using more than you do...
I confess to you about this because I feel very guilty...
I hope you will accept my sincere apology!

Man went home and had a big fight with his wife...

Few minutes later he received another message...
Sorry for my typo earlier, I mean your wifi
