Tudo sobre tudo

A man received a message from his neighbor:
-"Sorry sir, I am using your wife... day and night... I am using when you are not present at home... In fact I am using more than You are using...
I confess this because now I feel very much guilt...
Hope You will accept my sincere apologies"

... And the man shot his wife...

Few minutes later he received another message :
-Sorry sir, spelling mistake: wifi not wife.
