I, too, tend to be very protective of those I love. When I was but an itty bitty, well, about 2 to 2 1/2 years old...mom was dating a real asshole...threatened to cut off my fingers with a butcher knife once. Once my mom broke up with him, he sugared her gas tank. Thankfully, her dad--my grandpa--was the town's best carb' mechanic...he opened her engine and had the cylinders cleaned out and the carbeurator rebuilt inside 1 day, including getting it towed to the garage! They knew who did it, but his dad was a judge in town, so a complaint to the police would've fallen on deaf ears. The next time the asshole boyfriend came over, she ended up acting nice and friendly...and I went outside to "play" while they were upstairs--my playtime consisted of getting even, it was pre-planned: I poured a couple cups of sugar, and some water, in his gas tank. This was back in the 60's so there were no locking gas caps... Once he took his car to one of the town's mechanics to be fixed and de-sugared, mom got some money--all the town's mechanics knew he was an ass and it was circulated what he had done, so they all knew to charge him--but good--for the cleaning out, and also to take their time...his dad was not loaning him any of his cars, so he was stuck walking or depending on "friends" for a while...come to find out, he wasn't able to get around town that well.
