Odd priorities there. Like really a new one for me. Usually it's all the focus on the possible kidnapping, new technology, or the paper airplane, not... I'm assuming buying flowers? Unless you just happened to bump into him in a flower shop?
I love me some good avoidance every once in awhile, but this place is big and small. It might be hard to avoid him. But, I don't know, do you need a mediator? Someone along to help maybe talk things through?
