I'm seeing this all the time.
Mum with a buggy gets on the bus, sits down, gets her phone out and spends the whole journey ignoring her child as she is gossiping on the phone. The child tries to speak to the mum but is ignored. You see it everywhere, in parks, cafes, on trains. Don't mothers speak to their children any more? Don't they look out the window and show the child interesting things outside? I used to do that. The children are not learning communication skills at all as the mums are not interested.
Don't bother speaking to your kid, give him a pack of wotsits to keep him quiet till you get home and stick him in front of the telly. So sad.
