Sometimes we are down, depressed, mad, stressed, whatever it may be - but we choose to put on that smiling face like nothing is wrong. That is ok. I do it all the time and most people would probably say I am the most happy-go-lucky and outgoing person they know, but that is what they see from the outside looking in. It is okay to not be yourself 100% of the time. We all have bad days, weeks, even months, and that is perfectly normal.
