Almost everything that I got stolen was taken by friends or family that were alcoholics or drug Addicts, no matter how normal one of those people look like most times are they are not, I even had my brothers steal from me before, they won’t now but they did in the past so it’s hard to trust anybody,
I always had ashtray change/loose bills of about 5-7$ in my vehicles for emergency gas money whatever, that most all the single dollars, quarters and dimes/silver would end up missing every time I took my drummer friend to help him out by (who lost his license from dui) taking him to stores/gas station/restaurants while being at his parents house,
Most times when we were bringing in bags of groceries or bags from a resale store or just hanging out I would notice the money in my concealed ashtray was gone in the next day or so.
So I set a trap and marked a dollar and several quarters with black sharpie marker that said Hi and put them in the tray and one day after taking him shopping I said “I need some money for gas” he said “I got a little change that may help”
I said that will work and he reached In full pocket and took out a dollar and a few quarters that said Hi,
I took out of my pocket dollar bill and a couple quarters I didn't put in there that said Hi asked him to empty the full pocket which was full of everything that said Hi and embarrassed him in front of his mother, father and his baby’s mama and didn’t have anything to do with him ever again.
He committed several break-ins and burglaries to feed his habits and after that he got caught for several, he is still in prison as far as I know,
I could tell you other stories like that too,
Sometimes the closest people to you are the ones that are screwing you over,
