后端开发什么语言最难:请帮忙看看这段话是什么意思？谢谢了

Allan called a week later to say thanks for the birthday dinner and gift, and to tell me that, yes, he had taken the sweatshirt back and a gift certificate was being mailed to me in my name. What I said to him may have been because of what he did, or maybe it was just the extra long week I'd had. Or maybe it was because, as I listened to Allan complain and complain, I was put off by all the negativity. "Allan," I said in exasperation, "you know I'm your friend, and you know I'd do anything for you, but really, your woebegone attitude is getting very old. All you do is focus on how miserable you are. Pardon my saying so, but I think your 'poor me' shtick is very selfish. I'm going to make a suggestion. I know this is going to be a major undertaking for you, but I'm going to suggest it anyway. Tomorrow, take three $100 bills and go to that grocery store that's near your house. Walk down several aisles observing the other people in the store as you walk. The moment you see a woman with several children, one you know has more bills than she can comfortably meet, walk up to her and, without saying anything other than 'I hope you haves great day, ma'am,' hand her one of those $100 bills. Then smile and walk away. Just so long as you give it to a mother with a group of children.
