Walking
I don't know why people usually exclaim in seeming shock and horror and then look at me funny when I said I walk my dog around midnight onwards. What's the big deal about it?
I'm a night owl for one thing, and secondly I like the temperature around this time as it's just nice and cool if not cold. And most important of all, I don't get to see a horde of people around or worse other dog owners around! I like having my own space and letting my leash go slack and loose, allowing piglet_2005 lots of room to run about.
Midnight isn't the "oddest" hour I walk her anyway. On weekends, holidays or when I'm not working, I can walk her around 2-4am even which isn't that big a deal considering I'm wide awake too.
