person A: When I had to clear out my old bedroom when I left home_comma_ I really found it hard to throw away a lot of the stuff in there!
person B: Why do you find it hard to throw away old stuff
person A: Just thinking of all the good times I had with toys / books etc when I was a child! Even though I wouldn't use these things again_comma_ it was still hard to throw away 
person B: So what are you planning to do
person A: I ended up giving it to charity - that way someone else can have good times with them!
