To know another's features like no-one else has known
To know another's thoughts as though they were your own
To know another so well that you're never alone
I guess that's love
To know another's opinion though unexpressed
To know another's choice as to which is best
To know another's laugh from all the rest
I guess that's love
To know another's memories though time has flown
To know another's feelings though they are not shown
To know another's pain worse than your own
I guess that's love
Thomas Phelps
