Attaching Word files Email

[BBtoDroid]

I have taken this issue to three Verizon stores, BTW the Manager at the SF store on Post, Bang Lu, is one of the largest A$$-h0!&$ I have ever met because he lectured me on why I had not gone to the Verizon workshops on using the phone, and no one can answer it.

I received an email from a person and would like me to email a file, word, or excel or PDF, back to them.

HOW DO I DO THAT?

Thanks!
