Mexican Train Derailed

For those of you familiar with playing Mexican Trains, this view will be familiar. You pick out your 15 dominoes and the first thing to do is search for the start of your next train. In this case I was looking for a domino with 7 spots, which I clearly didn't have. 

My luck did not return, and I lost the whole game heavily. Fun to play, but less fun to lose, but good to be with family and able to play.
