I had a recent run in with my father in law. He has a car on permanent loan to me, although he occasionally uses it. A small dog ran out from nearside)) in front of me whilst on the move at about 40 kph ( small country road) . I braked but not too hard as neither my wife in the passenger seat not those in the back were belted up. Even so everyone in the car lurched forward. The little dog hit the front bumper on the offside, yelped, rolled a couple of times and ran off. The damage to the car was a small 4 cm crack in the lower half of the bumper.
As it is his car, instead of feigning ignorance as to the cause eg: dunno, may be it happened while parked in Big C car park or something, I thought that out of respect and honesty I should show him the crack and explain how it happened. He went ape <deleted> wailing as if it was the end of the world. He then spent the next hour repeatedly and theatrically opening and closing the bonnet loudly, looking underneath, starting and stopping the engine. Finally he stormed off, not looking at me, confiscating the keys so I could not use the car. Finally he calmed down after 3 days, returning the keys without a word. Honesty is never the best policy with a Thai it seems.
