Well, it's only a small house: 2 rooms upstairs, 2 downstairs and a ground-floor "wing" that holds the kitchen and bathroom. So hardly complicated, but it does have some oddities and really, is ripe for re-wiring.
I don't know which country you live in, but British homes are fitted with what are called "ring mains"; a separate loop of cable on each floor with the sockets in parallel around their feeder ring, and the ring having its own circuit-breaker. Mine also has a separate ring for the kitchen, and a spur to the lights and sockets in a shed.
Your question was about what's plugged into the sockets though - and some of the responses revealed that Britain may be unusual in most of the sockets being fitted with switches, so you don't need unplug an appliance after use, just turn the socket switch off.
(Though if you need work on the innards of the appliance, or could be injured if you start it accidentally, obviously you do unplug it as well!)
My Dad was a Chartered Electrical Engineer working as a scientist designing highly specialised equipment, not domestic wiring. He was also very practical, able to make as well as design circuits. He re-wired my parents' home completely in the 1960s, to the latest regulations and trade standards of that time.
