NB,
If you are unfamiliar with my previous posts, I will just cut to the chase by saying that I am an IT professional. I only bring this up because I would willingly pay a visit to a store at 4AM, probably have in fact, but not for detergent, unless I needed some. See, I cannot speak for anyone in the Cooper family, and I am not sure if IT people develop this out of habit or not, but I am a nite owl. This fits in with the IT realm, because a lot of work is either done after normal hours, so systems are not down during normal business, or things just take a long time to fix. I have worked over 38 hours straight on one project, and if the system is down unexpectedly, you pretty much have to work on it as long as you can keep going, or until it comes back up.
This, plus my normal circadian tendancies, and something of an occasional obsession with a video game or two, and I have stayed up until the wee hours of the morning more times than I can count. It seems that my "normal" bedtime is about 1 to 2 AM these days, and it has been later than 4AM. When I am in that mode, I have been known to grocery shop at 3. I am married, and strangely enough, my wife is much more of a morning person. I also do the majority of the grocery shopping.
