i think i may've posted about this one teacher before in another thread similar to this one... anyways;
there was this teacher called mrs. eels who'd always be pregnant every start of the school year (she had been covering our ict teacher who we had since the first year at my old high school. we were unaware of this.) during class with her she'd do nothing apart from play with her phone or give me the dirtiest look everyday.
pretty much got pregnant so she couldn't work there, gets money from maternity pay, goes back to work after a year, gets forgeted again and repeats the process.
