(3) Clothing. “But I need to be comfortable!” is the battle cry of the people who think that pajamas or various forms of underwear are acceptable clothing for travel. (Or even for court. But I digress.) There are many ways to be comfortable that do not involve sleepwear or gym clothes. I am not advocating ties and jackets, which were once de rigueur for flying. Rather, I am invoking the golden rule: If you have not showered, brushed your teeth, or cleaned your clothes, then would you like to be sitting next to you? As for shorts: No. Would you like to have a stranger’s bare legs against you for hours? Of course not. So don’t be that person. (I will recognize exceptions for Orlando or Hawaii, but that’s it.)
