Many people get caught up in the excitement. Initially, they might only invest what they can actually afford to lose. After they internalize pumpers' posts, convince themselves the wacky projections are reality, and hear others claiming to have larger holdings, they then aren't satisified w/ their smaller one. So, they start buying more and more eventually getting themselves into a position where they cannot afford to lose all the money they now have in the stock. It is most definitely reality not a drama. Some actually invest money needed for rent, food, and other essentials. When the price doesn't skyrocket in the time they expect or were told, panic sets in.
If you are an attorney as you claim, you should be able to grasp the concept that many people are gullible and have problems controlling their greed factor. Perhaps you and your friends might not experience this, but many people do. Some have not only gotten themselves invested but also convinced their immediate family, friends, coworkers, etc as well.
