Random Phone Call - I was sitting at home when I received a random

I was sitting at home when I received a random phone call. We talked for a while and caught up on each other's lives. I thought it could be a scam or a telemarketer. To my surprise, it was a friend I had not spoken to in a long time. It was a pleasant surprise and it made my day. It was a reminder that life is full of surprises and that we should always be open to them. But I decided to answer it anyway. It was from an unknown number and I was a bit hesitant to answer it....
