But the “tin man” answers, “I give these tins to my neighbour 45 (one) a week. He is ill and can’t work. 46 no one helps him, he will have big trouble.” I am so 47 (surprise) to hear that, so I ask him, “You mean you collect all those tins just to help your neighbour?” “I know this does not help much, but I just want to try my best to help.
