We have some friends who I love dearly but dread going out with because their perfumes almost make me physically ill. I've refrained from saying anything so far, but I may eventually.
You have no idea how off-putting that stuff can be on some of us. And I know you don't particularly want to hear from a guy, but our opinions count too, as do our comfort levels when we're around you.
Please, have mercy. You will be no less beautiful in our eyes, and we'll be a lot more comfortable. And you'll save a few bucks too.
