My previous guitar, a.k.a my very first one was very well taken care of by its owner (ME lol). No cracks, no neck warps, no nothing. Until one stupid day. Was at a jamming session with my friends, then one of them wanted to play with it, which was fine, the %@)^%)@#$&)@%*& thing was, when he stopped playing it, he just make it lay against the wall, and POOF, it dropped, paint chipped, heart hurt, lol
Second time was when I was practicing at home, then when I took off my guitar from the strap, its headstock accidentally hit the ceiling fan. The fan blade was dented, and my guitar had a small dent on the side of the headstock, lol xD.
