person A: I walked around the mall for 2 hours with my fly down.
person B: Haha.. I'm sorry_comma_ that made me laugh a little bit. I do that sometimes too_comma_ and have no idea how I can forget so many times. I think at least if it happens_comma_ almost no one can really tell or notice_comma_ if that helps.
person A: Unfortunately I had my shirt tucked in and I was wearing skinny jeans so everyone noticed they just didn't tell me.  I was wearing my superman undies too so it was extra noticeable...humiliating.
person B: Well_comma_ you could have been going commando_comma_ too. And shame on them for not letting you know. Let's focus on the positives--you can pull off skinny jeans_comma_ and you're interesting enough to want to wear Superman underwear. Keep it up
