I startle so easily--my kids take advantage of that ALL the time. Number 1 son got me one time ,but I almost got him. I was on the computer and he came within about 8 feet of me and turned on a bullhorn siren!! Within a split second I rose, kicked my chair to the side and was right there in front of him with my hands up and ready TO GO!! He got me that time, but I scared him pretty good , so he hasn't done that again. I'm gonna' get him back though!
One of my best friends annoys me. He does it on purpose. Little things like shaking up a pop bottle or a beer can. We all know what happens afterwards when someone opens them.
Son #2 pissed in his mothers sprinkle bottle that she uses for ironing!!!! She was a trifle upset when she ironed a shirt and couldn't figure out where that awful smell was coming from!!
