In your sentence, it should be “proves”, not “proofs”. That’s probably the sort of mistake you make in your map descriptions. I was not using “pluralis majestatis”, (note the spelling). When I said “We”, I meant myself and my three team-mates who play Joint Ops on LAN almost every Wednesday of the year, and alternate between laughter and despair at the incoherent, illiterate and misspelled map descriptions that we see. I then transferred to first person singular in order to give a personal opinion and a personal solution.
Yes I am offering to spell check. Did you fail to understand that?
