Just discovered a great practical benefit of having a self storage unit - solitude! Yes, it might sound pathetic but what a great excuse to get some peace and quiet away from the family, "I just need to fetch something from the storage lockup". Make a nice warm flask of drink, ward off the temptation to add something a little stronger. Chill for a bit, reminisce, recharge batteries, daydream. Return two and half hours later with a pack of light bulbs.
