Please, do engage in conversations with yougsters  10 and up you meet. You may meet a downright nobody angel like I did today- they are pretty obvious- very friendly. I also, today too, had a 3 years old talk to me at lenght but I did not catch half of what he said. I told him and wished him 'good luck with your plans'. It is really really fair to miss out on the talking. Go with the flow.
