How do you keep in touch with your relatives and friends?

Usually I keep in touch my friends on the instagram and kakaotalk. When I see great restaurants or cafe on the post of instagram. I tag my friends and we talk an appointment. I almost hang out my neighbor friends every weekend. But my hometown friends who live in a hometown still. I can\'t see them often. So we talk about more kakaotalk and we ofen call. I meet hometown friends when holiday. If I live in Seoul, when I want to keep in touch with person who interested and like. Then I find our common ground and try to meet that people. So I like people who similar with me. I think the important thing of relation is a comfortable. So I try to make comfortable relationship. That\'s the key point to maintain long relationship. It\'s hard thing to me that keep in touch with people. I like an old friendship. It\'s difficult to make creative with unknown person.but I have to try to contact many people. Because I want to make a lot of friends. :) That\'s a lot of jargon. sorry. ^-^
