One of my friends of 6 years he's a good friend of mine that owes me money it's around 100$ I told him to pay me he manipulated me and said "you said I didn't have to pay you back" which I didn't. After I told him you misunderstood and I still need my money he told me "no" now I need help what should I do should I fight him and use (law 5 so much depends on your reputation guard it with your life) I was thinking to fight him then we'Il just let it be and still be cool .i feel like he might brag that he didn't pay me back, behind my back maybe idk I carry my self highly and don't need that attached to my name or should I let it be and forget about it because I still want to be friends with him he's a good friend of mine but he is a narcissist and a manipulator to get what he wants. (what should i do to still be cool with him I can use him for things l'Il need in my currior?) any other opinions or options I can do? (The book I’m talking about on here is 48 laws of power)
