person A: When I was a teenager I used to borrow my big sisters clothes without her knowledge.  One time she had just bought a lovely new dress after saving all her wages.  That weekend I borrowed it and of course ripped it!  The next day when she found out she was so angry and i felt terrible.
person B: Oh no! I hope she's forgiven you since then.
person A: oh yes she has_comma_ it was a while ago now but at the time the guilt was awful.  Needless to say I learnt my lesson and never borrowed her clothes again!
person B: That's probably a good idea.
person A: Yes just a pity I had to learn the hard way.
