The trouble with having a large extended family is that you hardly get to be the first one to share your news with others. It is always someone else who does it for you.
The trouble with having your blog is that while you are the first one to announce your news, you can hardly talk to your friends and relatives because anything you say will be met with "yaa, I already know that, I read it in your blog"
Another trouble with having a blog is that since people are up to date with all your news, they hardly call you up. Moreover, it is always a one-way communication with no news from the other side coming your way.
The trouble with known people reading your blog is that you cannot bull shit without getting caught or do a healthy debate on "sensitive subjects".
And the trouble with kids growing up and reading your blog is that they know for sure that you love them to bits inspite of their mischief that make you superficially tear your hair out, because you then promptly go to your keyboards and type out a awww-inspiring version of those very annoying stuff they do, on your precious blog!
