It is better if you are other's friend help them to be better human instead of just having fun. Friends can protect and consult eachother in difficult , disappointing and happiness situations. They can also remind you that you can create your life in hard conditions. If you threw bad dice, you could play better in rest of our life. These friends are like voice of God! They are absolutely angel
with invisible wings.
I believe that angels are not unusual creatures .They are living with us if we will be righteous.
