Comments, mails, etc.

I need to reply to comments. I also need to reply to five or six important mails - some as old as a month or more by now. I also need to contact friends to plan my next visit home - the first 'proper' one, the first that isn't mainly for the purpose of moving.

People I love, people I miss, people I'm grateful to.

Why is it so damn difficult to actually write any of these comments and mails? Why do I keep postponing this until it basically doesn't matter anymore, even though the mails and comments I received made me so happy and grateful?
