So we hugged and I left Dan to the care of the airline - this time , however , not stuck in a wheelchair , and not shivering with a fever . So , much better than last time!I rode the trains back to Wada , uneventfully , except to say that I had to stand for an hour and a half or so , at the start of it all , as there were no seats left in the trains . I got back to Wada at 7 pm , and I took a taxi ( GASP , YES ) from Wada station to the old people 's home near my house . Why ?

Question: What may have Dan done the last time ?
Answer: None of the above choices .The airline took good care of him .He went to Wada to visit me .He got very sick .
