If you love someone, the feelings that you have for them will be conveyed to them even if you do not speak a word. Everything that is felt deep within your heart comes in to your eyes as a loving gaze for him or her. A warm embrace or nice hug can convey easily what you do not even say with words. Vice versa also happens with body language. If you do not want a person to come close to you and despise him, it will be clearly shown through his body language even if you use the most sugary words for him.
Other than love also, all feelings of the human nature can be expressed through their body language. It can be shame, embarrassment, hatred, openness, negativity, lies, nervousness, etc that can be judged just from the body language of the person.
However, when in love it is suggested that you use the proper body language whenever you are with your beloved. Whenever you meet him, do that with a smile and welcome him. However bad your mood is, he/she does not have to be the object of your bad mood. Give him/her a warm embrace so that your affection gets across to your loved one and say the simple words ‘I love you’. With the right choice of words and body language, you can make your beloved all the more special. Convey him your love and make your relationship very strong.
