There's little else to do but talk in the house and we all love gossip so of course Alex is going to talk about who he's met/seen whatever. At least he's done something. I've yet to hear Spencer speak about anything of the merest interest.
I don't think you can accuse Alex of playing the 'model card' he's been the first to admit he's been taken off the British books, he's not got the figure to do modelling for his age group now, he's happy to do catalogue work because it's a job to make money like any job at the end of the day.
We all do what we can to get through life and he can make a living by being photographed, though he's also well aware it can be short lived and he's talked of the future and the possibility of photography etc. He's never potrayed modelling as some dream job, it was really interesting to learn how models do the far-east market, lip model specialists and all that. Wasn't it Alex that encouraged Alison to follow up her modelling dream.
Alex has worked in a world where having a look or certain looks is just part of the tools of the trade. Spencer and Kate are probably used to being a in a small home area and being attractive makes them 'big fish in a small pond' I don't think they can understand that Alex isn't actually moved by people looks.
