This: you show that you are a total douche. Let others like your comments and statuses. When you like your own status that tells a sad story about you: you’re either terrifyingly alone or a narcissistic douche. In any case, you don’t need to cry out loud asking for people’s attention by liking your own posts. No way.
When you’re liking your own status is like you would curl up very-very hard and then kiss your own butt.
Mr. Beam says the same thing, but in a more fashionable way. Seriously, don’t click Like on your own posts.
