My Mums Friend past away

I was so sad when my mums friend past away yesterday.My mum cant stop crying because that she has no more friend to talk to anymore.She was only 44 years old and had not been married yet,then past away.She was sick on Friday.They were so closed friends in an old age.My mum wishes to go back in time and have more friends and learn till she works and have more money.But she cant go back in time.whaaaaaaaaaaa........
