How can I get into my school's locked wifi password

I know a lot of people think I just want the password to go on restricted sites and stuff, but that's not it
i want the password because I want to talk to one of my friends who lives 4000 miles away from me (literally) and by the time I get home, he'll be sleepping so at school is the only time to talk .

so if anyone has any good ways to get into the password thing, please help because it would mean soooo much to me because I miss him so much
again, this is for a good purpose and I dont intend to do anything bad for the school and stuff cuz,.....yeah u get the point

please help again, I would be grateful

Definition of "Rationalize" from Dictionary.com: "to ascribe (one's acts, opinions, etc.) to causes that superficially seem reasonable and valid but that actually are unrelated to the true, possibly unconscious and often less creditable or agreeable causes."

Your question is an example of a rationalization. If having the password was "for a good purpose," the school administration would help you. But you have weekends when you're not in school when you can talk to your friend and you can communicate via email during the week where they hold your messages until he gets up.

I know a way. Just email me at [email protected] and I will tell you.
