Here are some things that I've realized are quite important to me. Some of them disproportionately so.
A coffee mug needs to have a good thick ceramic (or possibly glass) rim or it is a waste of time. Is it wrong to ask what kind of mugs a person has before accepting an offer of coffee?
In the to-go variety, styrofoam pretty much ruins the experience, and even those plasticy feeling ones are not quite as good as the classic cardboard coffee cup.
If you can help it, always pee sitting down. Too much information? I was totally sold on this concept a few years ago and have never turned back. At first I felt like I was somehow less of a man for doing so, but how is it manly, let alone civilized, to spray urine all over the room? Have I said too much?
No pokes on facebook. Seriously. Don't poke me.
Try not to say "how are you" unless you mean it and have time to talk about it, and don't be offended if someone doesn't say "how are you". This social convention is so strong that I have trouble maintaining sincerity.
Well written dialogue and subtlety in television and film. Original lyrics in music.
Similarly, don't say you are going to pray for someone unless you are. I assume people who tell me they are going to pray for me actually do, but I know that too many times I've thrown this out flippantly and so I should try not to lie.
If someone has a problem with someone else and is telling you about it the first thing you should do is ask if they've talked to them about it. And since they probably haven't, the second thing you should do is talk about how they might do so. Again, there are social conventions here that are very hard to break.
When we are singing "worship" songs that use the word "me" or "I" when "us", "our", or "we" would be viable alternatives, I make the replacement. Not because "I" don't mean it or have nothing to do with it, but because we are just way too consumeristic and individualistic these days.
I do not want to see footage of celebrities coming out of buildings and getting into their car. Please don't show this to me. It makes me embarrassed for the human race.
Anyway, there you have it. Some are probably pretty important, and some probably are debatable, and some probably don't matter at all (and perhaps show I'm getting old!). Might as well admit them. How about you? Anything you've realized is of disproportionate importance to you right now?
