I'll attend a meeting with my old friend.
I received an email from an old friend.
He invited all of my family to attend a meeting yesterday.
He wrote he saw a family(not us) by chance at a shop Olympic.
So he thought that it was a chance to gather all of his old colleague.
All of us already be married. So it's little chance to gather.
Next Summer we all will gather together.
