You know ladies just love shopping. They can shop till you drop lol. On our many shopping stops I observed something rather fascinating. Mum was either shy or slow to decide or perhaps still retaining the thrifty habits of the older generation, not to spent unnecessarily. My wife and her sister would be extremely enthusiastic as if trying to make a sale, more so than the sales person present. They were trying so hard to pick the design/color which they think was nice but mum just wasn't interested. After a few days of shopping I found out that mum have a mind of her own. In their excitement to push their choice selection the girls were oblivious to this. On one occasion after all the usual suggestions by the girls and mum turning down all of them and the frenzy have died down; mum pointed to a particular piece from her wheelchair and said she liked that one lol.
All in all I'd say mum had a "Rolling Good Time" on this Shanghai holiday trip. She discovered that with the wheelchair it's possible to travel, Osteoarthritis of the knees not withstanding. She have became more cheerful and now without hesitation she would ask when is our next holiday.
