Yep. Visit my blog to find out if the house burned down.
If you have OCD, click 'like'. Then realize you didn't click it right, and click 'unlike', then try it again. Then realize that you could have done it better. Click 'unlike', then click 'like'. Then try not to think about it. Failing miserably, because it won't leave your mind, click 'unlike', then 'like', then 'unlike', then 'like' again. Wait. Wait. That wasn't clicked thoroughly enough. Unlike ...it. Now click 'like' again. Was it right this time? No. 'Unlike'. Now click 'like' again. Maybe that one was right.
Now start asking yourself if you locked your house doors or left the oven on.
Crap. This wasn't clicked right. Click 'Unlike' then 'like' again.
Ask yourself if it is right this time.
You already know the answer.
