One of my closest and dearest friends has become obese. She was always somewhat over-weight but she went from 250 to 380 pounds in the last few years. I've encouraged her to get healthy or stay active but she says she's happy. My problem is that she is my travel buddy. The last time we were on a plane together, sitting beside her VERY uncomfortable. On one of our last minute trips, we were unable to sit together. The person sitting beside her complained to the flight attendant and I truly believe they were going to tell her that she needed to buy an extra seat. I offered to switch seats so I would be the one next to her. I love my friend but she seems to think people on planes are simply being rude and obnoxious. I don't know what to say to her. We're planning a trip to Paris in a few months. How do I explain to her that SHE is the one that should understand? I can't sit next to her on a 7 hour flight to Europe. I don't want to hurt her feelings.
