Wife ??

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

Man then shot his wife.......
Few minutes later he received another message :
Sorry Sir spelling mistake... it's not wife but Wi-Fi
