Thank you! I generally much prefer black and white too, although I dabble in colour I'm more at home with mono.
You should give street stuff a go at some point, it's honestly not as nerve wracking as you might think. Maybe try it first with a camera smaller than a DSLR, people tend to notice you less with a smaller camera (I love my Fuji X100 for that).
I have a mirrorless jobby which is a little more compact so maybe I'll give that a go. I'll have to take the kids with me for protection!
Kids as unpaid bodyguards - sounds reasonable enough to me! 😄
