I used to get blamed for crap like that all of the time as a kid. Tools were the worst. Now I moved out and only swing by my parents a couple times a month and my dad still asks me if I have his tools.
My son Matt was always losing my tools, which he denied. That was until people started showing up and saying. Does this belong to you ?? I found it under the hood of my car !!
Matt works for a generator co now and has little time for side work. PTL
