Today I went back to the hospital where I had the twins. It was time to return the baby seats that we had rented. I was a bit nervous that they would find our cleaning of the seats inadequate. Fortunately, that wasn't the case. On our way from there, we had about thirty minutes to wait until the next bus, having just missed the last one by a minute. We decided to walk around the hospital, or at least almost, since there was a big machine digging up the ground and would have been in our way. So we walked and walked and walked and on the way back we ran out of time and almost missed the bus. Fortunately, the driver was nice and stopped to pick us up on his way out of the hospital area. While we were waiting for the train, suddenly we heard a big boom sounding a bit like a fast train roaring through the station area at full speed. Actually, it was a military plane flying so low I thought it would hit the electric lights. I didn't think it was allowed. It was quite scary.
