Hello,
Two friends are talking about a plan on opening a new restaurant. They are worry as investment is big.
A: "You think it is bound to fail"
B: "I think it might do anything"
1. What is meaning of might do anything? Is that exactly means: "I am not sure"
2. What kind of assurance in using 'might' instead of 'could' and can B said: "I think it can do something"?
