I did not know you call them "waistcoats" - I always wondered what a waiscoat was, now I know. The ones he bought are what we call pull-over sweater vests. They are very nice and make him feel better dressed. He is concerned now about the summer months coming up and not being able to wear the "vests".
They had plans to visit the Giant's Causeway and many other places, but had so much fun where they were in England. They visited Buckingham Palace, of course, and several other palaces and temples/churches and took so many pictures. I do not know all the places they visited. They stayed at a huge, historical hotel on the Thames and loved it so much they did not want to leave. I do not remember the name of the hotel, but it is luxurious and huge!
