Would you laugh if you.....?

Right today when I was on the bus, it was a double decker bus by the way. And I was sat downstairs at the front, and then the bus stopped at a bus stop with the doors open for a while, I dunno what the bus driver was waiting for, but then this lady started to come down the stairs and then when she got to the 3rd step she tripped over her own foot and then went flying down and hit against a window but she grabbed onto something and then she sat down and acted like nothing happened. Lool! Would you laugh if you saw this?? Cause the bus was so quite but there were quite a few people on the bus, and some big lady was sitting next to me and when the other lady tripped down the stairs the lady who was sat next to me just looked at her. I was holding my laugh in the whole way after that. But I feel bad laughing, but I just couldn't help it. Lol.
