Remember, as well, if she sends one messages to all of her contacts, it's counted as one message per contact. I know a few people who seem to think EVERYONE THEY KNOW needs to know what they're up to by text at any time, so they send text updates like "class sucks" or "I need a nap" to all of their contacts classed as mobile phone numbers. Same goes for picture messages. Besides, if she was at cheerleader camp, she was probably saying mean things about her slutty cheerleader friends to all her slutty non-cheerleader friends. Just for the sake of consistancy, let's say she receives and sends equal amounts of texts, which would put the sending end down to 17,500 in one month, or 584/day, or ~37 hour in a 16 hour day. This sounds much more realistic. Now, just to make things simple, an "all contact" text could send messages to hundreds of people at once. Since it's very hard to figure out, let's just say each text sent is received by, on average, 1.5 recipients, which puts actual messages sent to ~25, or one every 2-3 minutes. Even that is a very high number, but it's much more realistic.
