A bizarre PAGING issue

First of all, how do you send a page? THE PROBLEM:
I seem to be inadvertently leaving a PAGE to one particular friend (no one else). She said that a blank PAGE message appears with simply two brackets. She randomly got another one this morning from me and I swear I wasn't even near her phone number. Do little androids exist inside my phone trying to drive me nuts? Anyone out there experience anything like this? I admit I have happy fingers but this has gone beyond fingers that are happy, they must be exhilarated! It's like my phone is programmed to send a PAGE to her whenever it feels like it........ cuz and I don't even know HOW to send a page!!!!! HELP! ~Collette
