It does happen. Your first instinct to fix something is useally right, but laziness does get us all. Awhile back had 3 afghan about 3 weeks old. It was getting pretty hot in there so I added another fan up high. After I did it I thought ''man that dont look to sturdy, I should fix that better.'' Never did and 2days later it fell and killed all 3.lol. Live and learn.
