The Confusion of Bringing Refreshments and Its Conclusion

On a sweltering day recently, I brought refreshments to my son's club activity. The forecast that day had suggested it might even reach 40 degrees Celsius. I consulted with my son about what to bring, and we decided that ice would be better than the drinks everyone had already brought. We considered things like, 'It shouldn't be something that melts and drips,' and 'Since it's hot, something with a refreshing taste might be better,' and after much deliberation, we brought Ice Box as refreshments.

At 2:00 PM in the scorching heat, I arrived with enough Ice Boxes for everyone in a cooler, and the club members worshipped me like a god.
“Thank you! Thank you so much!”
Ah, that feels good! The kids are all so cute! There, there, there! Eat up, eat up! Don't worry about a thing! I was completely in bliss.

Then, at that moment, a first-year boy I had never met said something that made me doubt my ears.
“I would have preferred mineral water.”
“Huh???” I was so surprised my eyes went wide. I think I probably even made a sound. My moment of bliss ended abruptly. The club president's mother, who was watching nearby, was also shocked, and we looked at each other. She hurriedly scolded the boy, saying, “You shouldn't say things like that!” but the boy just looked blank, and seeing that, we were left blank as well. Oh, I was so surprised!!! What is wrong with you!!!

That day, after I got home, I told my son about it. My son was shocked, saying, “What! He really said that??” I made sure to emphasize to my son that he should never, ever do that, though I trust he never would. “I would never say that!” he replied, and that was supposed to be the end of it.

A few days later, my son came to me, looking a bit uncomfortable. “Hey, about that kid the other day... it just so happened that there was a committee meeting in his class today. I overheard someone who went to the same elementary school as him say that he had attended a special needs class for a while back in elementary school. I was wondering if that might have had something to do with what happened the other day...”
Oh... an unexpected turn of events... I couldn't help but look up at the sky. “I see. Thank you for telling me... Perhaps his characteristics might have had something to do with it. I'm sorry I spoke about it like it was a bad example...”
My son said, “I didn't know, and it can't be helped! Of course you'd be surprised!” but I thought about it for a while.

There are all kinds of children. You can't tell what a child struggles with just by looking at them. Even if we talk about diversity, human emotions are honest, and we can't always control them; we don't like what we don't like, and we get hurt... But there is no end to dealing with things one by one. It's natural to have things we don't understand or know, and sometimes a change in perspective can be a positive thing, but other times it can be a negative one. We don't even know which the other person wants. I truly felt that diversity, human relationships, and communication are difficult.

However, I was very happy that my son took this matter so sensitively, thought about it, and quietly told me. Because there is no single right answer, I felt it is important to think about the best approach at any given time.
Now, how should I use this experience? Maybe I'll sneak in a bottle of mineral water next time I bring refreshments. What should I do? I'll just go with how I feel at the time. Next time, I'll be able to handle it without being surprised. I'm a little happy about that.
