Maybe because I am also a substitute teacher and I have homeschooled my boys throughout their educational experience. I still have a 9th grader at home that I am still homeschooling. I have also worked in mental health off and on for the past 25 years, but my degree is in Biology. Go figure. I was strictly a SAHM for 15 years before reentering the workforce part time working weekends at a Group Home (psychiatric) as a Direct Care Worker. I quit that job and went into subbing, I only took the TSS job so we could have a steadier income than just subbing.
