The question asks about things, so I am not including people in my response.
If I am coming home, I have clothes on, my keys, wallet and mobile phone, so:
1. Desktop CPU (It's a Shuttle, so easy to grab.)
2. All my software and backup CDs (all in one holder.)
3. All photo albums and photos CDs (all in one box. All my original videos of the kids are off-site.)
4. Important documents file cabinet (small two drawer type, and it's on wheels.)
5a. If the wife is home: Put all of the above in the <1 year old van in the garage and drive it to safety. (and, if I have time, drive my POS car INTO the garage.)
5b. If the wife is not home: Grab the kids art folders (both in one place.)
