An emotional trap!

Each time I'm assigned an Audit, the first thing I decide is that I'll maintain only Professional relations with the people with whom I'll meet and interact and no attachments with anyone. But then people try to form it. Indeed, succeed as well.  They somehow trap me into different emotions and I fail and finally fall into it. (Don't worry even here they are girls only, always! :p) At every single Audit that I've done, there isn't even single one where the Accountant would not have said me that, if in future I get into practice then I should give them job in my office, that too without any interview, this was special request of the accountant of very previous audit, she had interview phobia. :) Then few want me to give them good Salary, more leaves, etc etc. Anything which they think has flaw in their current job they want that thing for them. Okay sure, is all what I say, I take it lightly. But then today was not something of that sorts. The Accounts Manager asked me chocolate for my good result. Then she asked me that, this time she is accepting chocolates but when I clear my C. A. Final I should meet her and give her sweets. I didn't wanted to say YES, for the sake of saying. So I said that, I can't promise but I'll try. Then she immediately asked that, will I forget her completely in future? I was confused as to now what I should say? So, I said that, my articleship will be over and I won't be coming next time for the Audit at their office and that this is my work, I go to different places and meet different people and then after few days I'm back to office. So it's mostly short term for all.
She is very emotional person, I didn't wanted to hurt her but it is like this. If she will get emotionally attached to me then one day I'll end up breaking her heart, though unintentionally but still.
