Fantasy Role Play.
As kids some of us probably played cops & robbers, cowboys & Indians, soldier, and other things like that.
---------------------------
I made a fur-trimmed helmet and chain mail shirt, strapped on an old ritual sword and went to costume parties as the accountant for a Central Asian warlord. It was a simple job, I did head counts, pointing at the ground and counting in the thousands, or kept track of the Khan's property, which was everything in sight.
For the Renaissance Faire job I made a black wizard robe and acted the part by magically fixing the caterer's 'vintage' equipment from stoves and fridges to a walkie-talkie.
