Peaches you are someone I could definitely work with.  I wouldn't say you take your job too seriously, I would say you sound like you do your job to the best of your ability and do what is expected of you, and more.

I've had a think about this and I do believe PA's all work differently.  What I also have to remember is, this PA has worked with the same boss for about 15 years, been in the company maybe 20.  Whereas I am new, here just over 18 months and yes I do work very differently and sometimes it can be frustrating when others don't act/re-act how I think they should.

I guess I shall just have to do my job and keep chasing for the answers I need, frustrating though it may be.
