I can't come up or think of a noun and verb that would describe a situation, where 2 or more people made different statements about some situation and both are not sure if their statement is correct, but they presume that it is.
Two friends made 2 different statements about the opening time of a store. One stated that it opens at 9, another - at 8.
They did not:
- have a quarrel
- make physical/monetary bets
They just each claimed that their memory about the store's opening hours is correct.
Verb: "Me and John _______ whether the store opens at 9 or 8 and he won."
Noun: "Our ______ with John about the store's opening time was won by John."
How would you name the situation (noun) that they had and call the action (verb) that they performed?
