Is it so hard to apologize?

Hi Guys and Salam~

Today, i just got back from some exercise and want to collect my cloth that i sent to MUrni for Dobi yesterday.. well, i send it by plastic bag because its hard to deliver it by a bucket by a motor. so the time i collected the cloth, i was scold by the owner because of the plastic bag.. he said that it cause him a lot of trouble especially when the cloth were finish being washed and want to put it bag in the bag plastic. Well, i agree it was my fault so i apologize to him and promise that i will never do it again =.=' and suddenly something come into my mind about our learning, why we never admit that sometimes we done it wrong and deserve to get punishment? We still learning, and it is normal for us to do some mistake and we need to apologize for it.. dont let ego control ur mind .. release it, be humble and apologize.. its not hard if u let go ur ego and received the punishment.. just say sorry.. is it so hard? well, we need to think about that.. im sorry if i hurt anyone because of this essay because i already experienced it..
