Things I Would Lock Away if I Could

If I had a huge lockbox I would lock our fridge, thermostat, my dad's pills, the front door, and the keys to the car away in it, and only my mother and I would know where the keys were kept. I know this doesnt make sense. How would I keep our front door locked up in a box. The point is that these are the things that cause us the most problems with my dad. He sneaks out of the apartment when ever he is able. He eats and sneaks food whenever my mom or I are not paying attention, and it is not just snacks he is eating either. He has started to forget when he has eaten meals. So, he will eat lunch and then an hour later he will get up and start to make himself another full meal thinking he has not eaten. Several months ago we had to take over administering his pills, he could not remember when and what to take, or if he had even taken them. So, he would end up going without or DOUBLING his dose for the day or night. This led to locking away all the pills in the house and just administering his pills as he needed them.
As for the thermostat, remember when you were little, and you came out in the wintertime to complain to you parents that you were cold? Mine always told me to "put a sweater on" well if my dad is the slightest bit uncomfortable, too cold, or too hot, he comes out and adjusts the thermostat. It doesn't matter if he is cold and only wearing a short sleeve shirt he cranks the heat up and roasts the rest of out until we realize he has changed it. So, these are some of the things in my home that I would lock away as to control some of the chaos a little.
