My job is a bit different as I am a teacher but TBH sometimes i am just desperate for some me time! I work FT though, sometimes I feel like there is ALWAYS a child asking me or telling me something or touching me. DOn't get me wrong I love my job and my class are fantastic but sometimes it would be nice to spend a couple of child free hours a week!!
At least if you are only PT and the kids are with the X sometimes you would get a break. i would take the job on trial just in case its not what you expected or the lady has crazy expectations!!
