We plan to purchase one of those propane portable heaters for February, November and December. A friend of mine had one this past season and we used it a few times.
Another conversation:
Dad "Is everything in your bag?"
DD (eye roll)
Dad "Please check. Remember when you left one cleat in your room?"
DD "OK" (huff-puff) "Yes, everything is in in the bag."
Dad "Good. And everything is in the trunk?"
DD "YES!" (strains eye rolling muscles)
At this point you go to the car and check that the bag is in the trunk and everything is in the bag. Retrieve missing items from wherever they have been strewn. Repeat as needed from age 5 to 18.
