['I told my friend I needed to borrow money for some car repairs but I used it for something else completely. I feel bad about it.', 'Oh no. What did you use it on?', "I don't even want to say, I'm so ashamed."]
Oh I'm so sorry. Hopefully, you've learned and won't do it again, yea?
I asked my friend for a loan but I used the money for a different reason.
