Well, if we want to be pedantic, and of course we do, I'd say the stickers are a form of self-expression and the comments are a form of expression, some of which seemed cynical and/or biased due to most of those laptop lids featuring a high proportion of innocuous logos, video games, ironic meme culture stuff, cute animals, some flags, and if I really look for it, some resembling vaguely anti-authoritarian themes
It’s interesting the top comment is a self expression against people’s self expression against the self expression of the stickers.
Everything here seems to boil down to self expression. Even the flags and downvotes of the content at the bottom is a form of self expression.
This comment is my self expression about all the inception of self expression.
And now my brain hurts.
