Tockstein wrote an offer to purchase a house owned by Rothenbeucher. Tockstein signed the offer and personally delivered it to Rothenbeucher. The offer included a condition that acceptance must be made within 24 hours.

At the end of that 24-hour period, the offer would be automatically revoked if Rothenbeucher had not accepted. Rothenbeucher signed the agreement within the 24-hour period.

However, he did not deliver the acceptance to Tockstein personally, as Tockstein had done with the offer.

Instead, Rothenbeucher delivered the acceptance to his own real estate agent, who delivered it to Tockstein after the automatic revocation time.

Tockstein claimed that the offer was automatically revoked when Rothenbeucher did not deliver it within the specified time period. Was Tockstein correct? Explain.
