Just a quick story about losing my mind...
In the middle of the night I woke up to get a drink of water. I grabbed my glass from the side table and took a drink. As I went to set it back down on the coaster I realized something was wrong. My coaster kept lighting up. Ugh, so annoying, I'm just trying to go to sleep and my coaster keeps lighting up. I tried setting my glass down lightly then picked up my coaster and pushed a bunch of buttons to turn the light off.
At this point you probably realize this is a pretty intense coaster, but I didn't think about the fact that my coasters do not light up at the time. I just needed it to stop so I could go back to sleep.
When I woke up this morning I looked over and noticed my water glass balancing on my cell phone. I immediately remembered my struggles with that dang light up coaster last night which apparently turned out to be my phone. I'm glad the water didn't spill.
That is my story.
