Coming back to Iowa

I arrived on Saturday night, after taking three planes, a panic moment at Beijing airport, a lost plane in Minneapolis, another lost baggage and 13 hours of difference.
On Saturday morning, while I was checking in at the airport I had some trouble with inmigration. I had to buy a plane ticket from the States to Spain so I could probe that I'm going to be here less than 90 days as a tourist. I bought my ticket and then the computer chose me to do a security checking. I almost lost the first plane.
The stop in Japan was cool and nothing unexpected happened. But when I arrived in Minneapolis more things happened. I was waiting at the immigration line for more than one hour, then I spoke some words in Chinese when I was supposed to be speaking English, and I was at gate B and my plane to Des Moines was from gate G. I tried my best to take it but I didn't make it. When I arrived at the gate my plane was leaving the airport. I had to wait for another couple of hours until the next flight.
I arrived in Des Moines around 7pm and one of my suitcases didn't arrive! I went to the help desk and the assistant told me that my baggage was in Beijing, but I just saw it a few hours before in Minneapolis. I was so confused, disappointed and worried that I couldn't believe why my baggage was lost again.
But I have good news. On Sunday they called me and they found my baggage, they delivered it at home and everything is perfect again.
