Encourage Education.

One sure way to show someone how much you care about them is to encourage their education. Find out what they have interest in and encourage them to learn more about it. It doesn't have to be a full fledged college class. Maybe a course on photography or a dance class what ever their interest you can find a course or class somewhere to suit their desires. Now you can't just be supportive when they start their learning process you have to stay interested in what they are learning. Let them tell you what they are learning and if you have interest in the subject you might learn some new things too. Listen intently and try to understand their passion in this subject and be their biggest supporter. Now if you have a desire to learn about something do it also and share with them. Learning will never dampen your relationship and you both will be better off having the most knowledge you can. Pure love will flow from your heart when you mind is happy so educate and stimulate.
