I started out as a horticulture professor but now teach college and secondary Spanish. The kids haven't changed much over the years but boy, the parents have...they'll be in there in 2 seconds screaming if their darling gets a 98 instead of his usual 100. Even on the college level. I haven't had to deal with parents actually harassing college profesors yet but some of my colleagues have.
My husband teaches secondary science. Two of my daughters who are already degreed in other fields may go into teaching.
