Talking is the gerund.
Personality is an important part of an interpersonal relationship with another person. In relative terms, personality is just as important as how someone appears. When you hang out with friends, you have to like their personality in order to get along with them. You don't hang out with people who annoy you, or who just aren't anything like you. This is because you prefer different personalities. When you are attracted to someone physically, you should also like talking to them. If you do not enjoy talking with this person, than their personality is what is bugging you. Some people may not be physically attractive to you, but if you still enjoy talking with them, than they have a personality you like. Take for example, you may not like a friend physically, but you love talking to them. You are attracted to them by their personality.
Seems to be a bit rude from your point of view but from his point of view he's just greeting another friend.
If you are talking about a friend that is a member of the "furry fandom" another way of saying "Furry Friend" is "Anthro" or "Friend that likes furry stuff" Some suggest the term "Furiend" but it sounds improper when used in normal speech.
Talking to my friend.
Start by talking to him and getting to know one another - the friendship will follow if he is interested.
Yes, "talking to my friend" is the gerund phrase.
