So yesterday i finished my semester in law school and the librarian was giving me shit about not returning some book i never took

so while we're arguing this cute chick comes by about similar problem but she had the good sense of bringing a book to replace the lost book which coincidentally was the exact book i needed so when the chick found out that she actually has given the first book back she starts to leave, i seeing my chance slipping kinda chased her down and flirted my way into her giving me the book but then i noticed she's actually really hot and so i got her name from the librarian and invited her on facebook with a message thanking her about the book.
She then replied with: Your welcome

) i love helping out people in need but its interesting how i had the book you needed!

Now i'm thinking about asking her out but i feel like i need to build up to it but i'm really having a mental breakdown here so i need help guys please give me something!
