Colleagues say they envy me for being tall, but I can't say I can't get married. Is this cheating? I really can't get married.

Each has his own merits, but they are all looking at one mountain. Tall people envy short people, but they don't know that short people also have short people's troubles. Similarly, short people envy tall people more. In the eyes of most people, they are tall, slim and look good in clothes. They don't have to wear high heels to look good. It's just a joke to tell you that you are cheap, but envy is true. Don't worry about it. It's not that you can't get married, but that your height doesn't match and your choice is small.
