[Q]: My son needed his diaper changed just a few hours ago. I noticed that his diaper had a distinct smell and felt full, so I carried him back to his changing table. I laid out a disposable diaper in his size and baby wipes. I took off his shorts and his dirty diaper, using it to clean up some of the mess from his bottom. I folded it over so that the outside that was clean was underneath him. I then used the wipes to clean up any mess that was leftover on his bottom. Once he was adequately clean, I grabbed a new diaper and slipped the back under his bottom. I made sure to talk to him throughout the entire process, and gave him a rattle to play with so that he was distracted. I pulled the tabs on the sides of his diaper across the front and secured them around his waist. I put his shorts back on, picked him up, and threw away the dirty diaper. He felt much better and was ready to play afterwards. 
Question: Did they throw away the old diaper?
[A]: Yes


[Q]: It was a quiet late afternoon weekday with about 4 other tables being occupied . Of course , apart from ordering coffee like The Fluffy ( espresso with milk and lots of foam ! ) ...... we couldn't resist sharing a slice of Tiramisu ( RM14/USD4.20 ) which is usually the safest and yet boring choice when one has trouble deciding . The cake slice was rather messy and we weren't sure whether they meant to serve the cake with the strawberry stuffed into the side of the cake like that ! 
Question: Why were they ordering Coffee and cake ?
[A]: They wanted to sit and chat over coffee .
