1. Jack likes Jill 80% of the time with an intensity of 75%

2. Jill likes Jack 70% of the time with an intensity of 65%

3. When it's a sunny day, 6 times out of ten sunny days: Jack and Jill will go up the Hill

4. When it's overcast, or raining: they go up the Hill 1 out of 15 overcast days.

5. When Jack and Jill are up the Hill:

    5a. Jack likes Jill with an intensity of 80~99%

    5b. Jill likes Jack with an intensity of 76~90%

6. there is a pattern of quantum fluctuations in Jack's liking Jill based on the extent to which Jill likes Jack.
