HIV does not make people dangerous to know, so you can shake their hands and give them a hug: Heaven knows they need it.
Other Diana, Princess of Wales quotes:
I think the biggest disease the world suffers from in this day and age is the disease of people feeling unloved.
You can't do anything good that you don't feel in your heart.
Carry out a random act of kindness, with no expectation of reward, safe in the knowledge that one day someone might do the same for you.
