Well it sounds like these two ladies were extremely insensitive, but being overweight and being under sensitive are not necesarily two things that go hand and hand. I know a lot of people who are weight proportionate to height types who have similar (or worse) sensitivity problems.
No one on this planet is perfect. Everyone has flaws and shortcomings. Unfortunately I wear mine on my sleeve. (Actually it's in my sleeve and my shirt and my pants etc

) I live a sedintary lifestyle. I am extremely busy person who has developed the bad habit of eating on the run and eating food that is not the best--but is convienent. Is this the best way to live? No. It is a shortcoming...but I know other less visible, but FAR less becoming shortcomings. I like who I am and have accepted my difference within myself. There are many other people in this world who have decided to not like me due to the superficial reason of my weight. That is their less visible, but far less attractive shortcoming.
