What if we can do telepathy?

Once having seen X-men, people would be strongly impressed by professor X’s supernatural ability of telepathy. Some people told us that they would do anything and take whatever result just to own such power. But when it comes to one of us having that telepathy, we would rather not use it.
First of all, using telepathy on people around you, especially your beloved ones can destroy your social relations since you are able to read their minds, opinions. Imagine when you can read someone’s mind, you can also see what they don’t really like, even hate about you that they keep for themselves. After seeing that, your attitude towards them will change, such as your behavior would become ceremonious. The situation gets worse if you saw people’s secrets. What would happen if you couldn’t hold yourself and tell someone about that secret? The one who will be hurt is both of you and the relationship between you two will be badly damaged.
Another downside of telepathy is that you can foresee other people' plans. Although this is good from security’s point of view but to your emotional life, telepathy does you more harm than good. Suppose your friends want to make a surprise birthday party for you, but you saw it all thanks to your ability, and then you came to it with no surprise, your real behavior would upset everyone. And the same thing would go for all other surprise things in your life and spoil your relationships.
Bringing that special ability to the workplace, it would make you feel frustrated in your work since you are capable of reading your superior’s mind. If you handed in a project, and you read in his mind that he thought it was bad, you would probably give up. But in case what he really meant that the project was bad now and it needed more improvements, you would lose an opportunity to prove yourself as you had given up already.
Finally, when people found out about your special ability, most of them would distance themselves from the unusual one, which is you. Some people could have a discriminatory look against you because people have a natural tendency of being scared of the unknown. You will face a life with isolation more than social communication, lacking in everyday transactions…
To sum up, although telepathy has its pros and cons, the downsides are still superior and that’s why we choose not to use it.
