No matter how busy a person is, if they really care, they will always find time for you.
When a person is really interested in you, they will take time to show how interested they actually are in you! Anybody can give away a material object. You can give a person gold, money, or diamond rings if you have it to give, and may not even really worry about it, because material things can be bought over again. Once money is gone, a person will almost always have the opportunity to make the money that they once had, back.
