difficulty to understand a pun

Good Afternoon, Klein! I have been very busy these day, so I didn't check your feedbacks for more than a week. I'm really catching up with your feedbacks now. It is very hard not only to understand a pun that you have made, but also to make a pun by myself. For example, I am not able to understand what this statement means with regard to SEWOL tragedy. "Those who carry too many buckets start feeling pail." I am willing to enjoy making a pun by English even if I am poor at making a pun. I hope that I will have a opportunity to understand the pun what you will make in next class. I appreciate your dedicated help. See you next morning.^^

A pleasant afternoon to you [이름]! Thanks for dropping by despite your hectic schedule. Your note here just made me smile. Please read everything carefully and if you notice something incongruous, just let me know. Now, let\'s discuss the word pun: \"Those who carry too many buckets start feeling pail.\" Pail and bucket are the same but since this is a play on words, we need to listen carefully to how the words are spoken to get the deeper meaning of the entirety of the verse. Pail is the homonym of PALE, which means lack of intensity of color, brightness or strength. If we carry too many pails or buckets, we will definitely feel pale or weak in the end. As for my question: \"Do you think the crewmembers of SEWOL ship are carrying too many buckets that\'s why they are starting to feel pail?\" you may interpret this in many ways. It is possible that buckets here signify verbal bashes from many Koreans and the cases that the SEWOL crewmen are facing and so, it is highly probable for them to feel mentally weak, even disoriented. It can also be read as sarcasm due to the fact that not many of the surviving SEWOL crewmen saved their passengers, which can be represented by the \"buckets\"; so do you think they feel pail [=pale]? Why would they feel weak by not doing anything, other than saving themselves? How I hope I have given light to this pun. If not, we can still talk about it tomorrow, can\'t we? Please prepare a pun and let me decipher its meaning. Thank you [이름]! May you continue to have a WAN/WONderful afternoon. That\'s a pun! Are you going to wander around before heading home later? Hopefully, not. Go straight home [이름] and have a WONDERFUL time with your family. Stay safe! _Klein Good Afternoon, Klein!
