Ah! Well, first, I think that it can be readily apparent if the person is a romantic--a man who opens doors for a woman, pulls back her chair, brings her flowers. A woman who reads romances, watches romantic comedies, listens to love songs, yes?.traveller. said:What others can see or perceive about the person in question. First impressions and things readily apparent.
Likewise, it can be readily apparent if a person is gallant and/or has noble sentiments--that is, a person who gives up their bus seat for a pregnant woman or someone who is elderly.
I'd guess that this is someone who tends to be emotional--cries easily, laughs easily. Body language and expressions would make it *very* evident that this person feels great empathy and sympathy for others, as well as the fact that they might be sensitive or moody--emotional changes in a person are often very obvious. And, finally, I'd say this is probably someone who tends to touch others. Is more likely to lay a hand on a shoulder, hug someone, take their hand to show he/she cares.
Would those suffice as externals?
