the 53rd line is missing a – sign
hi there is this the type your after please email me

well grant here is the web address address , they have 30% disc at the moment , tell them michael recommened you
hi kevin if you are still in need of them i think this is the web address
filling address ,ring them if you need them in a hurry ,say martin netsims said you would sort him out
I didn’t understand anything in this code
Interesting polisbisities, and will probably allow people to take the steps they need to get help at their own pace. (Like WebMD, only more concrete!) I hope this is the start of something great. Like Fallen Angels, I think it will help with stigma; it might also be good for, say, children of people with these disorders who are just beginning to manifest symptoms.
try to make it as a short program
its really big
That’s just rude, how could he do that? First he interrupts the library, back-chats the librarian and treats Emma like a scab! That’s just mean!! Poor Emma, but I bet this will backfire on Pat The Rat’s face once Jason tells Emma he likes her! (I can tell theirs a little somin’ somin’! ) But shame, I also felt like crying for the poor girl, please send her my wishes Nikki. Tell her “Lulu’s here, don’t worry girl. He be tr&!#ini#8217;p&p8221;
what is the variable f in display_poly() function??
– Oh, Brianna! She is so lovely. Love her locks=) We haven’t chatted in so long! Would love to catch up in the new year – maybe a coffee or lunch date. How did 4 years go by so quickly? This is Lilah in a few months, to;o#8230&Four sounds so much bigger than three…
