Absolutely not. A "friend" who steals from you is someone that you can no longer call a friend. Also the fact that they did not think it was a big deal just goes to show that they are not aware of their own faults and bad decisions. Over the weekend I had a party, someone who I have called my best friend and said he was like a brother to me stole from me. He took over 30 thousand dollars worth of merchandise. He went through all of the jewelry boxes in the house and emptied out all of them, took electronics from wherever he could find them, and just about anything else that he might have liked or thought had value. He did this while everyone was around, he just apparently would sneak off for a minute or two and start emptying things into a backpack and did that all night long. Someone who was driving him home noticed an item I said was missing and let me know so the police arrested him and found him with some of the stolen goods but plenty of them are still missing. Hell, he went through peoples wallets and took credit and debit cards from any of them that he could get access to. Went to his house the next day to pick up something I had left there and somewhat confronted him about all of this stealing. He literally acted like he had done nothing wrong, like nothing had happened, and wasn't understanding why I was so angry and disappointed with him. I will never speak to him again after this because the level of betrayal is beyond comprehension for anyone who knows him. He couldn't even come up with a reason why he did it, just that he was going to pawn anything he could for money. So the fact that someone I called a friend committed such a terrible act means that he is not actually a friend. It seems like you are in the same boat, if someone you call a friend takes things from you they betrayed you, they broke a trust which you had with them and depending on how badly they've hurt you decides if it can be repaired. Trust is a major foundation on which friendship is built and if you cannot trust somebody how can you be friends with them? In situations where trust has been broken that means that friendship is broken. Someone who would steal from a friend is someone who is toxic and needs to be cut off and out of your life. Obviously if this person was watching your house you trusted them a lot and they would be a close friend but taking stuff is something that just destroys anything between you. End everything with this person so it doesn't happen again.
