Seattle is full of weird looking creeps. This is beyond the usual and the kid aspect should alarm people but when you live in a city like that where there are freaks all over the place all the time it's a different atmosphere. In a lot of areas of the city there's a super liberal, anything-goes kind of mentality and those kind of people would probably think "oh that's neat how weird" if they saw someone like this, aside from that aspect there's also just a really strong mind your own business kind of vibe in the city in general.
