Interesting?

For the past couple of weeks, I've been hiding from a classmate of mine... who just doesn't seem to get a clue.
The last time I entertained her visit to the house was disastrous! The thing is that once you make her a little comfortable, getting her to leave is like prying something burnt from a pan... and it's not the non stick kind of pan either.
Since last week, she has practically come to the house every day! There was a day when she came twice too. That day she came in the morning but it happened to be that I was actually home alone and asleep. I'm a heavy sleeper and apparently my sleep was deep enough to not wake up to the dog's barking. When she came back later that afternoon, I was at the mall in San Fernando with Mom. Billy's girl friend gave her my new cell phone number not knowing that I am trying to keep it within a limited amount of people... thank goodness she had only wrote it down on a piece of paper and lost it.
She came the night before last night and I hid in the bedroom. She was talking with my mom for an hour and looked like she had no plan of leaving. I was on Facebook and when she left she went to an internet shop and caught me on Facebook. She asked me where I was and when I was coming home. I told her I was faraway and coming home very late. She was just like 'Oh cool, I guess I'll just come by tomorrow.' I practically pulled my hair out.
She came again this afternoon. I ran to the bedroom and hid there again. Billy just came home so I threw a brush at his window from mine. He was laughing about the situation but didn't leave me... I love the crazy things that my cousins do for me! We were at the window, just chillin, for about 30 minutes. Then my classmate decided to finally leave. She still thinks that I am leaving to go back to the States tomorrow so she told Mom that she'd just come back tomorrow morning. My jaw dropped to my knees, this girl is worst than a stalker.
I made a plan with Billy. If she came, I'd wake him up so that he can 'take me to the airport'. He was cool with the plan as long as she didn't come before 9. Billy doesn't come home from work until around 4 in the middle of the morning... so he's asleep until about 10 or 11. He said that if she came before 9, he'd be mad and yell at her.
It's really weird because I really don't want to be mean but it's like she's abusing my kindness towards her. And for those who are reading are probably thinking 'She just wants to say goodbye!'... not that's not how it is.
She wants to see me before I leave so that she can have my cell phone and other things that I won't be taking when I go back to the states. It irritates how she'll only approach you... or hunt you down... when she wants or need something.
