Being a respectful guest

As much as I love Japan and would leech onto any opportunity to live + work here... Rocky and I are very much guests in this wonderland. So, a couple rules vary from our everyday in Hong Kong, for example- we're not supposed to dispose of pet waste in public bins.. and the way Rocks and I wander the city all day long means I have these poop bags clipped to my backpack for hours.. my double tying + double bagging it might hide the smell but it's still strange and unsightly...!
