Loan them money
Friends are friends. I don't attach any value to them above enjoying their friendship and company. Not sure what your question means.....
Be the friend you want a friend to be!
If you're my friend, you are ALREADY valued by me. 😉
You can't put a value or price on a friend. A friends unwavering support or love is priceless.
Value your friends and their unique qualities. Work toward developing a good circle of friends. Ask for ideas from older, experienced ones.
Know more than they know.
the person who deserve value will get automatically value
Sure thing.
Make sure to leave them in their original packaging and away from direct sunlight. Actually any place anywhere in a tepid dark dry place should keep them in Mint or Near Mint condition so when it comes time to sell them, they will be worth more.
Sorry the Question seemed funny to me . . . Adding value to someone is rather odd, BUT in times like these our friends and acquaintances do have certain value when considering "Social Networking". Although I do not search out people for what they can "Do for me", life happens, and as we stay in touch and move from job to job there may be a company one of your friends moves to that might provide you with a better position. A friend within that particular company would certainly have additional value rather then just the social one.
