At work, there's only two girls on my IT team.
Manplaining all day, every day
I'm not employed in that field (due to my belief that computers - and anything else involving electricity - work by magic), but I can only imagine. I have a close male friend who is a senior software engineer - he's a very, very intelligent guy, and in the past has worked for organisations such as Microsoft, the British military and NASA. He currently works for a company that also employs several seriously shit-hot mathematicians, one of whom is a woman who he rates as by far the most intelligent person he has ever met - and he's often shocked by the amount of mansplaining and casual misogyny he sees her having to deal with.
