lots of good points there.... not much to add to that,,, but im going to come in at a different angle...
if youre new to chatting up girls like this then you need to talk to her quick while shes still new and before you decide youre in love with her. (maybe that sounda abit harsh... but you know what I mean!)
and... you work with her, so you have a million and one reasons to talk to her...
you work with her... so youre not going to chat her up one day and have her in bed that night... if I were in youre situation Id try to talk to her and get to know her for a week before I asked her out....
plus if shes new to youre team etc.. she might be a bit nervous...
and lastly... the thing with chat up lines is... any bollocks will do.... if she likes you then she likes you, if not then youre wasting youre time anyway...
the last chat up line I used was "do you like my socks"..."theyve got red bits".... "theyre really cool"..."I got them from asda"...
(Id had a lot to drink)
...but it worked
