As they say, there are two rules in improv: Never say no, and never ask why. When another actor asks 'Why?' or says no to something you're suggesting, then it's very clear that they're putting the onus on you, because they're not comfortable with it themselves.
My grandpa didn't believe in hugging and kissing, or saying I love you. His love had to do with the way he treated you. When he said, We're going here, we're going there, he was telling me about life. That was his love for me. My love for him was listening to what he said, keeping out of trouble, doing right, being fair.
