Ugly arms, sun protection, hairy arms, scars, marks, blah blah blah. I would like to add; please don’t ask them, “oh my god, aren’t you hot!” they are wearing long sleeves for a REASON and whatever that may be, they certainly don’t need to be reminded by you that an 80 degree day is hot! C’mon people have some common sense. They are either hiding something they are self conscience about or maybe that’s just how they like to dress. Either way, they know when it’s hot outside and you’re only making it worse.
