When someone calls you after something that affects them,
generally in a
bad way, just to
talk on their way home.
It is done for the companionship of being walked home when the person can't physically be there.
"thanks for talking me home from the pub last
night, I was too drunk to get home on my own"
"I was talked home by my friend last
night when I couldn't make it alone" "that was
nice of them"
