person A: I have an older friend who I try to help out.  She lost her husband a couple years ago. 
person B: Thats very admirable of you.  How do you help her?
person A: We go out to lunch regularly.  She is depressed and I try and get her out of the house to do things.
person B: We need more people like you in the world.  Theres always someone out there who needs a helping hand and could use a friend.
person A: Thanks.  Yes she had some mental issues around the time he died but is doing better now.
