And she was going on to him about how she had taken all her friends to a flash restaurant last night and booming about how it was so nice to take 20 of them to this restaurant as they didn't have enough chairs at home, he's like 8 or 9, does he GIVE a fuck that his mother is a sad flash git who finds the need to let hte whole train know??
On same lines as maisemor, what if there was something that meant he couldn't read? or that his mother wanted to keep him occupied with cosy chat so's he wasn't anxious? Or something. I talk away to my 8yo ds on the Tube in a way that probably isn't the way other mothers talk to their 8yos - he has some language problems. Occasionally I think "I must sound like an idiot to the other commuters" and then I think "So what ds is more important."
