(hymmm It depends on what context a person is refering when they say you are compassionate. One could be compassionate with one's career, hobby etc.???) In terms of doing voulunteer work (or whatever the case is) doing something you love and being totally dedicated to it dispite what others think of you is compassionate in my book.
In terms of relationship wise in my opinion its really hard to convey compassion in words. You have to show it. You show it through your gestures, your body language, how you touch and kiss the person. Littel gestures like giving gifts to a deserving person and so forth.
I want a girl who likes to talk. ......I just dont know what to say sometimes and would rather just listen.
