Phone talking 2nd week in Jan : Do you have a special way to keep a relationship?

Let me explain about what I thought

First one, contact when a special day is coming.

You don't need to do a great dffort to contact them. Just talk with them even only 5 minutes or send a text message to them. You might think this is nothing, but for them, they feel they are still concerned by you.

Second thing is share a time with them to use a common interest. 

Each person has a lot of ways to spend a spare time. Sports, Watching TV or movie, Talking, even studying!!! So, for man, you will be able to get along to play sports or drink with them. And for woman, I'm not sure but just listen to their story or go shopping, watch a movie something like that. This method can take you to a great relationship I think.

Last one, use a SNS(Social Network Service). 

In this time, there are many tools to communicate to each other. You already know, twitter, facebook, cyworld, blog. So, All you have to do is sign on a site, leave a comment. And they will reply. 

Not only SNS but you can use e-mail or letter. I think write a letter to use your hand is more effective and better way then type up with machine. Because when you got a real card or letter, you can feel their great sincere mind.

These 3 things is only I can think. And I wonder if you have a good skill to keep in touch with your buddy^^
