Michael,
you should know that we live in very tolerant SE23 although it seems that those advocating it have forgotten its meaning. (One can find it here http://dictionary.reference.com/browse/tolerance)
So how about some tolerance for parents? (as they are the enemy number one on this thread)
Brian,
I don't know where you live, but I see a lot of good behaviour all around. I see a lot of dedicated parents, a lot of fathers taking children out which was not the norm when you or I grew up. I have experienced youth on the busses who are willing to help. On the last few trips my toddler was falling asleep and young guys with a hooded tops (would you believe it) have helped me get the folded buggy off the bus. I simply asked for help. You probably agree that I deserved help, as I was considerate to fellow passengers and folded the buggy in the first place. But had I had a monster buggy which was full of shopping would I deserve your help in moving out of my way to get on / off the bus? Your answer will show you how tolerant and open minded you are.
