How did we go from this to THIS?

Yesterday we finished at the dentist at 4:30 and I looked at little princess and said "So... what do you want to do now?"

"I don't know... get a car wash?"

"You wanna do something crazy?" I asked her slyly.

"That depends," she replied warily.

"We could grab our suits and go to the lake."

"Seriously..."

I'm rarely home before 6 pm and then there's dinner to make, mail to read, chores to do but today it was just me and little princess with a good four hours of day light to kill. We ran home and changed into our suits, grabbed towels, a cooler, sunscreen, and toobs, and were back on the road in under 15 minutes. We picked up soda and snacks and arrived at the lake in 45 minutes. There was only about 5 other families and plenty of room to spread out. We lounged in the lake and talked and laughed and told stories and teased each other while eating pringles and cookies in the water. The sun was warm on our faces and the water warm on our bodies. We packed it up around 8 pm hungry and happy. We picked up burgers and ate them on the sofa before getting ready for bed. I'm not sure about little princess but I sleep great. It was truly a great day together.

Then there was today. I got home close to 6 pm and immediately started fixing dinner. I wanted to go to the gym but it was already getting late so I thought "hey, little princess and I could do an exercise video together and spend some more quality time together."

I had her help me clear the living room and popped in the video. She said she didn't want to but then again she says that about almost everything. I told her I didn't care, we were doing it. We did the warm up exercises and I looked at her and she wasn't doing anything, just standing behind me. So I said, "Come on, put your hands on your hips" and she yelled "I'm NOT DOING THIS!" and stomped off to her room. I yelled back "Well, YOU CAN STAY THERE THEN."

I'm amazed how we went from connected and fun one day to yelling at each other the next.
