Well, last year I had a clogged toilet. So I was in a jam. Actually I can’t remember that exactly but.. anyway to solve this problem, you know, I searched the Internet. And I followed the way that I saw the Internet, but It didn’t work. I couldn’t call a plumber because it was so late. So I just tried to get a hold of the situation. But I failed all the way. So next day, I ended up calling plumber. And so I was forced to pay a fortune for repairs.
