Kindly let me share with you my "borrow your bag" story.
One day I was picking up my then 7 year old daughter from school when I got a call from my husband who was at work.
DH: "Karen (a girl who worked for him) is going on a date tonight and was lamenting not having a nice bag like a Chanel or LV to go on this special date. I told her you had lots of them and she could stop by and borrow one of yours."
ME: Complete silence, followed by the thundering sound of my jaw dropping and my eyebrows furrowing....... "Pardon me, I don't think I heard you correctly. Did you just say you offered Karen something that doesn't belong to you? Because if you did, that's a problem, because my answer is unequivocally--NO--for Karen or anyone else for that matter. I am astounded that we even have to have this discussion."
DH: "Well, I can't tell her no, now, I already told her she could."
ME: "I see you are in quite a self inflicted quandary. Deal with it. The answer is no, and you need to resolve it."
Later, when he got home, he had recognized the error of his ways, saying, "I don't know what I was thinking.....", so I let it go, but my 7 year old didn't! "Daddy, how can you offer mommy's bags to someone? Only I can get to wear them!", and walks off shaking her head.
I cut him some slack but when we went to bed that night, before he turned out the lights, I asked lightheartedly, "do you want to go see a production of Hamlet?" He answered, "Uh, I'd rather not, why, are you going to one?" I replied, "No, but I thought you might need a reminder of Shakespeare's advice to 'Neither a borrower nor lender be'". And he laughed, shook his head, turned off the lights and never offered my bags out again. To this day, I don't know what he was thinking.
My best friend, who I relayed the story to exclaimed, "WTF! Does your husband even know you? I have known you for over 15 years and I wouldn't borrow a bag!"
I can't imagine anyone asking me, but if they did, I wouldn't hesitate to tell them that I live by the motto, "Neither a borrower nor lender be", and that would end all discussion. I truly wouldn't want to ever borrow anything, because, aside from a slight germ phobia, I would be completely paranoid about something happening to someone else's property. I would be too busy treating it like the Queen's crystal so I wouldn't enjoy it, so no, I don't borrow, and I don't lend.
