BIB last time I was in Cardiff was before I ended up in a wheelchair.
We got the bus from the hotel into the city centre.
I was amazed that it seemed everyone who got on the bus, seemed to know everyone else on the bus and were very happy to include strangers (me) in their conversations!
Bear in mind Cardiff is a large city, but it seemed more like a village with all the chatter.
I live in a large city in the South of England and people here are no where near as friendly.
Wales is nice
although the Welsh speaking elderly ladies who seemed in charge of every charity shop I went in, could be quite scary but that was in North Wales
