Well, you might be curious about my qualifications as this is a big — big topic and expertise might be required. I won’t lie but I am pretty well qualified to write this. I am pretty habitual on getting a NO. If you bet right now on whether I will get a NO again, you might win! Though proposing and getting a NO is not a good habit as such.
Listen to the person you are proposing till the moment before you propose and from the moment right after you end proposing. The listening time after proposing includes listening to his/her reply with an open mind. The time, while you propose, is yours and can only be taken from you if you get interrupted by a slap, kick, punch or any other way by the person you are proposing.
The only way of knowing a person is to love them without hope.
