Do you have a friend you haven't spoken to in a while? Why not give them a call and ask how they are?
It can be great to reconnect with an old friend, and there's nothing better than a good reminisce. Why not pick up the phone and find out how someone is doing? You may be fascinated to find out what they've been up to, and it may feel great to share your experience with a friend too. It could make their day as well as yours.
