Having no idea how to say 'No', I see it as my weakness, and I choose not to respond, trying to avoid. If possible, I wish I could runaway! At the same time, it can be very powerful , I hate to admit that ignorance works the best to reject offer sometimes, but it is true. It might be cruel to someone. However, the one who tends to ignore, will feel guilty as well. So, at the end no happy ending~
