Scales, Purging, and Stupid Ignorant Facebook Guys.

Well, the battery in my scale died, which kinda upsets me.  So I need to get a new battery soon.  If I don't it might drive me insane, all this not knowing... I don't know for how long I can do that. I base how much of everything I do on that scale.  It's like a friend. 
On a good note, I still haven't purged since my last slip.  I'm almost back to my 30 day goal.  Hopefully this time I can beat my high of 81 days.  My new goal is 90.  I'm just not sure how much harder this is going to be without my scale.
 
Sometimes Facebook people irritate me.  This guy, who's 29, started messaging me and stuff.  The whole time hitting on me, and he knows I'm 19.  And now he's telling me I'm weird because I spend a lot of time with my sister? Plus, because I basically act as a mentor to her and the group of neighbor kids, I'm a complete weirdo? Where does he get off saying that? I even told him about how I want to go into psychology and work with youth, thus I'll be doing this a hell of a lot more.  It's basically like a youth group.  And, he's 29 hitting on a 19 yr old, isn't that a bit odd???  I'm 19, spending time with a sibling and mentoring a group of 11-16 yr olds and I'm weird, but a 29yr old with kids hitting on a 19yr old is "normal"??? What the hell planet is he from?
