1. Say thank you after you are given advice
2. Find something they are wearing and ask them about it. For example, they are wearing a silver bracelet, well ask them about it. Where did they get it, who gave it to them, is it real silver, ext. Being their friend is more than anyone can ask for.
3. Or instead of #2, just say thank you and leave. Let them give to you. Giving is one of the Universe's gifts to us. What we give we receive in abundant amount. So let them give! :)
