When traveling alone without my kids,normally I’d have my earphones on Tbh,I too can’t stand noisy commutes So it’s on ME to find ways to deal with it AS A GROWN ADULT instead of wanting kids to be the mature grown adult If I don’t have a cheap $5 earphones with me,then I just deal with it.After all,the time I need to hear these noises is not as long as their parents needed to hear them,because I’m a parent too🥹 Also I’d rather kids doing this compared to the elderlies. They’re worser imo.
