Input:  Person1:       I would much rather see her once or twice and not do anything about it — — what could I about it anyway ? 
 Person2:Don ’ t say things like this . Please be confident . I think you still have the chance to win her love , unless you don ’ t love her anymore . 
 Person1:        Don ’ t you think she is a bit out of my way ? 
 Person2:In some way , she is more modern . 
 Person1:        If I do try to do anything , I ’ d only be sent off with a flea in my ear . 
 Person2:If you really think so , in my opinion you should give up this feeling completely .
