yeah if i do anything with her, i think i'll have to let her know what's up beforehand. she seems to be the kind to get attached. 10 years ago, i would have banged her and never talked to her again.. i've done that a few times, and the co-dependent chicks made me feel guilty. i guess it's better to be older and wiser.
Don't do it like you would 10 years ago...these things may really hurt her personality and even that small mistake could turn her into heartless bitch later, just be wise and not selfish.
