For some reason, instead of having a twist-lock plug and jack, we have four separate plugs for one of our three-phase power supplies. For a while, I would plug and unplug without turning off the source. Then, I thought about the fact that the plug is hot when it gets part way into the jack, and I decided to take the extra precaution of powering down every time before plugging or unplugging.
I still remember the day when, at about age 3, I learned to keep my thumb out from between the prongs of the plug when I plug in the lamp. ;-)

Ahhh...memories. Like the time a outlet wall plate broke apart while my parents were plugging something in. Naturally, they told me to stay away from the outlets until they could buy a new plate.
Naturally, I didn't. Ouch. :-)

It depends..
In Australia, the telecommunications industry classifies 42.4Vac rms or 60V dc as Extra Low Voltage (ELV) which is generally considered the point where dangerous voltages commence. See page 12 ->
I was either plugging in or unplugging my Christmas train set. I think I was a bit older than you. I couldn't move my finger and had to pull away my arm, IIRC.
