I would not like to be one of those sad internet girls. To be fair, I have never been. For a really long time, I did not have my own laptop — this is also how I have missed out on most films even made throughout human history — and posting constant updates about crossing eyes with your crush or hating school is not that easy from your dad`s laptop.
I set up a Tumblr account when I was 16 or 17, but most of what I did was reposting fashion or tattoo photos, so I obviously have not been aware of its full potential. The other thing was, of course, that where I came from, Tumblr was not that big — the same with MySpace — and my English was not improved enough, my knowledge of Western culture was not sufficient enough to participate in the scene. The only time I have put my Tumblr account into good use was when I posted a short story I have written, in English. Looking back on it now, I still think it was quite good, for my age and my proficiency of the language at that point.
