What have you done?

Bob was gone for most of the day so I was able to catch up on some things around the house today.  After supper I decided it would be a good day to clean the oven.  It is self clean and this will be the first time I have done it.  Can't be that hard.  I put the instruction book away so I am on my own.  Hit the clean oven button - ok, now it says lock the door - ok.  Whoops, I forgot to take the racks out.  Now, start over.  After locking the door the numbers 4:00 came up.  This will take 4 hours?  When it started to smell like burned food I knew I wouldn't leave this on for 4 hours.  My eyes started to water.  I have had enough.  I shut it off and opened the back door.  Bob will be home in 2 hours.  Shouldn't be too bad by then.  Yep, it was.  His foot wasn't in the door when he piped up, "What have you done now?"  He expected me to say I burned something.  When he found the culprit was the oven, he wanted to know why I picked today to do it.  His eyes started to burn also.  Now he is really complaining.  I laughed, it will take a few minutes for them to stop.  Good thing I don't do this often.  We would all have to leave the house for hours a day.  Might be a good way to get him to go shopping!.....
