2. (5 pts) a landscaper subcontractor signed a subcontract with a gc for a specific scope and price. the scope did not include watering the new grass seed to get it established, which involves temporary irrigation lines and sprinkler heads. the project was going well and towards the end the landscaper sent an email to the gc saying, "i’ve decided to water the grass for you." the sub later decided to buy his entire team 80’s retro ski jackets instead of watering the grass. was this a valid, legally enforceable contract to water the grass? why or why not?
