Youth work. Carefully consider teenagers' life

This week I'm trying to help with preparing some decorations (and decorating maybe) for Halloween at the youth center I voluntery work. But I think I went a little bit far with some of my ideas that now I realize that I should consider more carefully some situations and young people around me. The thing is that I do not know them well, so I can understand if anything troubles them why and what. I'm trying to say that you never know about bumping into other people's skeletons from their closet. Especially, when you're involved in working with some vulnerable teenagers around. I feel bad I do not speak Finnsh and can't approach them anyway in their native language. Because as Nelson Mandela said:

If you talk to a man in a language he understands, that goes to his head. If you talk to him in his language, that goes to his heart.

I want to talk from my heart and there must be another way to do it! That way is ART in my case. I can't help it. For me ART is more bearable than life and its disgusting true hard reality sometimes. There is a lot of dying and death in my old skrap art trials but this is my way to conquer personal pain and lost of beloved ones. I protest and mock over prosaic daily life by art. Also, I know I can't keep my black sense of humor inside. It is unfortunately, very often misunderstood.

To the second botom line of this entry:

On Monday (Oct, 26th) I painted some fakе styrofoam "gravestone" and then I think I went a little bit (a little bit!) far into tricky, weird, or spooky Halloween spirit, painting "see you soon" on it, when there are some quite young people sick enough with their difficult life and probably don't need such mocking over life anyway. I apologize if I offended anyone. I did not mean ti at all.

However, I painted something for the first time since 2 years and 3 months (july, 2013). I stoped any painting or drawing when I went to US. I couldn't. I lost all kind of inspiration. Back at home in august 2014 'til now I haven't done any sketch or something... until now. Strange... I feel I want to start painting as my hobby and passion again... 
Thanks, Turenki!
