Casey was a cow that lived on the farm. Casey chewed the cud.
How would you describe Casey?

My family and I decided that the evening was beautiful so we wanted to have a bonfire. First, my husband went to our shed and gathered some dry wood. I placed camp chairs around our fire pit. Then my husband placed the dry wood in a pyramid shape inside the fire pit. He then set some small kindling ablaze using a long lighter. Once the kindling reached the dry wood, it set the wood on fire. We then sat around the fire for some time, adding more logs as the previous ones burned out. We cooked marshmallows on sticks over the open flames. When the marshmallows were golden brown, we placed them between two graham crackers with chocolate pieces. We ate our S'mores as we joked, laughed and told stories around our beautiful fire. When we finished, I put away our camp chairs. My husband made sure the fire was out by dousing it with some water and we went inside to bed.
Who started the fire?

My wife and I decided to invite some friends over. We wanted to clean our and house and make it look good after it was messed up by my daughter. One of the first things that we did to clean was to get out the vacuum. To do so, I opened up the door to the closet and got it out of there. I took the plug and put it in a socket that was close to the area of the floor that I wanted to clean. I hit the power button and the vacuum started to make a weird noise. I opened the vacuum up and cleaned the inside out. After that, it was ready to get started. I pushed the vacuum all over the floor in every part of the house. It was very loud and it was nice to push the power button and turn it off when I was finished.
When did they start vacuuming?
