To be happy and smile is a really important thing to do in life! It gives you so much that you would not expect. The stress calms down, you won't be sad or depressed. If something hursts, sometimes the best thing to do is to just laugh your way out of it!
Tomorrow I turn 16 and I am super excited! To bad I also will find out wich subject I will get for the exsam, I just hope it's not math!
