I stumbled across this letter on Facebook. It looks to be from a radio station page that is based in Saskatoon. I'm not sure what to think about it:
On one hand, they didn't demand that everyone comply and makes things 'safe' for their timid child. They asked for folks to comply. I think that they are asking a lot, but if you never ask, you never get anything, so it can't hurt to ask.
On the other hand, how far is society supposed to bend over backwards to make everyone feel included in everything? One can't argue that this is a life-threatening situation, like with allergies. The child is just easily scared. That doesn't sound like something that society really needs to concern itself with.
Maybe if the parents feel this strongly about it, one of them (or both) could walk the neighborhood first, since they know their child, and figure out which places are "too scary for now" for their child. Then make sure that when they bring their child around, they skip certain houses (which is likely what'll happen anyhow, as I doubt that every neighbor will comply with this request)
Just seems to me to be a lot to ask of a neighborhood. Most of whom probably have never met or know the child in question.
