This is sooo true! She's just jealous. Take HiHeels et all advice and take the higher road. She sounds like a charmer. Is that why her husband has had to turn to substance abuse?
My sister-in-law #1 can be catty. My favorite was telling me that if I had a Hermes bag, I needed the Hermes wallet to go into the Hermes bag. She said this to me not even knowing how many I have or knowing I have Bearn Wallets. I have never discussed them with her. She lives across the country and I rarely see her. I don't travel with Birkin or Kelly, just Bolide or Trim so that's all she has seen of my collection. I have never let on about any of these bags because I didn't want to hear the commentary from her. As previously discussed on the site, many family members don't get it or are jealous. I just avoid the subject completely with people like this.
