Living overlooking a busy highway sure can make it tough to fall asleep at times!
Although the noise doesn't always bother me -- at times the steady-traffic sound is even lulling -- but I need to admit that maybe the noise is just a convenient reason why I've been burning the midnight oil too often. (Other than the fact that I'm really a night owl. I just love staying up late -- doing writing and reading and other things I won't reveal.)
Unfortunately, though, it's just a heck of a lot easier to get my zzz's later -- like when the traffic dies down after midnight -- which, of course, leads to my being naughty and not going to be earlier.
