Answer 2

It looks like you have a series of sentences with missing words or incorrect verb forms. I'll help you correct and complete them:

1. He didn't let me lay (lay) with his watch.
2. I wanted to go to a university.
3. He didn't let me play (lay) with his watch.
4. She heard someone open (to open).
5. Granny didn't want to marry my Dad.

Please note that "lay" is the past tense of "lie" (to recline or be situated), while "play" is the correct verb for interacting with a watch. Also, "to open" is the infinitive form of the verb, and it fits in the context of someone or something being heard opening, e.g., a door or a window. And finally, the correct verb for someone's desire not to get married is "to marry," not "to go."
