My sister had been working really hard ever since she became an HVAC technician. I thought maybe she was trying to prove something, but I also thought that she needed to get a rest from working so hard. She was signing up for emergency HVAC hours all the time, and while she was making good money, she was becoming exhausted. I talked to her about this and eventually I was able to get her to see that it would be a good thing for her to recharge. We both talked about what she could do for a vacation, and then we saw this commercial on the TV about this really nice cruise line. They were having a good deal on the cruise, and we looked at each other and smiled. We both decided we would go on a little vacation together. She didn’t want to go by herself, and I also felt like going on a cruise would be great. So we booked the cruise for both of us. When we were on the boat, it was so fancy and nice. The room we had was perfect with a nice balcony to look at the water. The climate control system was fancy too with a nice smart thermostat as well. We were able to adjust the temperature control settings in our room with our smartphones, and that was a fancy feature. My sister was saying a lot of good things about smart thermostats and how they save you huge money on the energy bills. She said it was smart for them to use smart thermostats on the cruise ship. We ended up having a fabulous time.
