A thousand faces

I'll show when I'm mad happy or tired But not when I'm sad not when I'm lonely or when something is wrong I'll pretend everything is alright and nothing is bothering me or I'll get pissed to hide that I'm scared I'll scream but hide my tears and I won't show you my fears I won't let you too close I won't let down my walls and I won't let you in so I won't get hurt ever again
