Or you can say something like this....
"If you lie hard and long enough... then it becomes the truth.." So, for those people they have been lying for a long time and they now believe it to be true.

Oh.. btw... I don't lie because what is the point... it will be cause problems later...

Are you using a router?

If so, what kind of security encryption are you using? If it is WEP... you might want to switch to WPA or WPA2... that if your router has that encryption. Don't use WEP because there are software out there to crack the encryption.

If you are on a wifi, are you using MAC filtering to prevent others from connection to your network?

You might want to change your DHCP ranges or switch it to static IP instead.

This might be too technical.... sorry :( but usually in my field when we see messages like this... we do a security audit on our network to check for hackers.
