On August $15,2003,$ Wilbert Heikkila signed an agreement with Kangas Realty to sell eight parcels of Heikkila$$s property. On September $8,2003,$ David McLaughlin met with a Kangas agent who drafted McLaughlin$$s offer to purchase three of the parcels. McLaughlin signed the offer and gave the agent checks for each parcel. On September $9$ and $10,2003,$ the agent for Heikkila prepared three printed pur$-$ chase agreements, one for each parcel. On September $14,2003,$ David$$s wife, Joanne McLaughlin, met with the agent and signed the agreements. On Sep$-$ tember $16,2003,$ Heikkila met with his real estate agent. Writing on the printed agreements, Heikkila changed the price of one parcel from $$145,000$ to $$150,000,$ the price of another parcel from $$32,000$ to $$45,000,$ and the price of the third parcel from $$175,000$ to $$179,000.$ Neither of the McLaughlins signed an acceptance of Heikkila$$s changes to the printed agreements before Heikkila withdrew his offer to sell. The McLaughlins learned that Heikkila had withdrawn his offer on January $1,2004,$ when the real estate agent returned the checks to them. Totally shocked at Heikkila$$s conduct, the McLaughlins brought action to compel specific performance of the purchase agreement signed by Joanne McLaughlin on their behalf. Decide.
