I went back to work this year after a 15 year break to be a SAHM. I went from retail management to education, the job I got was not where I was placed, due to departmental changes, I'm not where I expected to be, although, I do like this job. I also ended up in a full time position but had only been expecting 3 or 4 days. It's been a massive change!
Among other things I am finding hard, is a few attitudes. I loved my job pre-children, worked with some lovely people. Most of the people in my new place are lovely. There are a couple, and one in particular, who I just don't know how to deal with.
I think very much a spade is a spade, I am the same person each day, whether happy, sad, tired etc, I'm still the same to people, polite, nice, friendly. One girl, one day can be chatty, friendly, the next day, ignore me, another day, speak over me, another day be purposefully awkward then the next day make me a cup of tea. I have found she will literally step over me to get what she wants, answer questions for other people to me, reiterate something which I have just said but louder or more authoratively, or perhaps act upon something happening which I have chosen to ignore, heavily discipline something which I have only perhaps just lightly dealt with (kids behaviour etc).
I am- being nice, friendly, normal, not letting it bother me (as such), getting on with my job. I'm sure I'm doing the right thing. I just don't know how to "deal" with people who don't show you their true selves. Folk with many levels- what do you do?
I'm too old for this shit, I'm not going to take it to the manager, but lets just say, the day she's not there, is a very normal day at work, the other days are a bit 
For those well experienced in office politics, what do you do??
