being stupid

What happened tonight is called “being stupid.” I forgot to take my key out when I went to dinner. At the moment, I thought I was extremely silly. I tried to climb the window but I still could not get into my room. I could not do anything but called my renter. Fortunately, he came and gave me the backup key. After getting my key, my friend and I went to dinner. The second time “being stupid” was happened. I forgot to collect my change and gave all the money to the clerk. When the clerk told me that it was too much money, I knew that I was being stupid again. I have been so stupid a day that no one could be more stupid than I was.
