I've fallen for someone wholly inappropriate in an embarrassingly adolescent way, to the point where I find myself doing ridiculous things like saving his voice-mail messages to re-listen to and getting excited about using the same pen as him ('cos he's actually touched it too). 
I am self-employed and he is an occasional client. I ended up chatting to him at an Xmas lunch today. He mentioned that he is thinking about getting a PA in 2014. I jokingly suggested that maybe it could be me. To my surprise he has seriously taken me up on this and sent me an email this afternoon pretty much saying the job is mine if I really want it!!
OMG it is tempting. Imagine getting the opportunity to spend all day with - and organising the life of - somebody you are that nuts about. Yet career-wise it would make no sense. I am much better off in every way working for myself and have worked hard to build up a good client base, which I would have to abandon. People would wonder what the hell I was doing. PAing isn't even related to what I do.
