People you know always look different on tv.
We have yet to see Boo and Jill on tv (soon I hope) so I don't know what that will be like, but one of the presenters on the local news programme has a house across the road from Brian, and it is odd when I watch John on the tv. He is much smarter dressed - suit and tie instead of jeans etc - but he does look very different.
I have a video of Brian conducting on tv many moons ago and he looks very different from how he does in real life.
One of my colleagues in Barry library was on a local news slot about a big day they had in the library on Saturday, and a local writer who I also know was there as well and they both looked different too.
Why is that? It isn't like watching people on home videos, there is a sort of glass wall between the viewer and them. It is odd.
