Just some info for newbies who don’t know anything yet - Stragbasher is a charming, handsome, and blond white man.
…and that’s his real hair.
Just out of interest, how much is he paying both of you? 
Oh, I might as well add my 2 bits. I’ve done a lot of different jobs and found the week or two I spent subbing as an ‘English teaching assistant’ for a kindy in HK to be incredibly stressful, despite it being only six hours a day. I was extremely happy to leave! I think a good part of how stressful you find a job depends on how good a personality ‘fit’ you are to it, which only you really know (referring only to the job bit and not management, etc. - if the job’s worth it, you can usually manage to put up with that bit).
