Women are weird. They're exceptionally passive aggressive, and they love gossiping like there was a fire sale on it. It doesn't help that the few female OT's that I've had to shadow were not my cup of tea. I didn't think they were nice at all, and I could see them being overtly political or passive aggressive. Also, as others have mentioned in this thread, there is a very real bias I may have to contend with as a male in a female dominated profession.
Currently, I want to work in pediatrics. I like the idea of working in the schools and with kids. However, I DO see that others, especially women, may view that with a wary eye. It sucks.
There is a bright side though. If you're a single guy, damn, the women... Lots of pretty women. That's something that I don't miss about tech.
