To Err is human

Today after dinner, I was buying some apples from a little boy sitting in the chair of his father. I asked him, 'Can you sell apples?' He replied,'yes'. I was thinking him little boy and also thinking about the boy's family. That time a man came and started playing with a mango. I was thinking whether this man is going to exploit this young child. Anyway, nothing happened like that. I bought .5 kg apple costs 55 TK. I gave the boy 100 Tk. He returned me 45 TK and I was demanding 55 Tk. I just forgot that I gave him 100 tk. I was thinking .5 cost 55 tk and I bought .5 kg and he should cash me 55 tk back. Suddenly, that man said how much I have given to the boy. That time I felt that I an wrong and the boy is correct. I was thinking about that man but with a great surprise I noticed that my activities was likely to exploiting the boy. I felt shame and could not forgive myself for doing that. We demand ourselves educated and a bit different.. and was thinking how could I...?..but that time I remembered..education makes better human but not above human. and making mistake is a notion of human behavior....so the proverb comes 'To err is human'.
