A lot of people think that having a conversation with their crushes can be the most awkward thing that can happen. This is not always true. You can have a conversation with your crush that will be fun and exciting. You can make some effort to know more about the things that your crush likes.
You can then formulate easy questions that your crush can answer easily. It will allow your crush to have fun in your company and it may lead to a longer conversation. The less awkward that you become with your crush, the more conversations that you will have in the future.
