On January $26,2022,$ I contacted, over the telephone, a former student of mine at Purdue, who baby$-$sits our two sons and asked if she would sit for us on February $14,2022,$ from $5$:$00$pm to $11$:$30$pm$.$ She agreed and the pay would be $$8\mathrm{.}00$ an hour. My wife and I planned on having dinner in Indianapolis and seeing a play. The sitter said she would take care of our boys. Because of this quiz, I decided that I could not spend that much time on entertainment, so on February $13,$ I called the sitter and told her that we wouldn't need her the $14$th$.$ The sitter tried to get another sitting job on the $14$th$,$ but was not able, so she watched television that evening. What contractual issue$($s$)$ are relevant to this situation?

Question $16$ options:

Since it was not in writing, it is not a legal contract.

No genuiness of assent.
