That feedback is actually very mean!
Our home welcomes volunteers from everywhere, of all ages or cultures since 2015. Some have been incredible people and others not so much while others have benefited to the maximum from our offer while others didn’t feel much about it. It all depends on the openness of each participant to bring his best self and help how he can do best.
You unfortunately didn’t do much in terms of fair exchange not to mention that everyday you had a chance to describe anything you see for improvement but you apparently preferred gossiping in cliques.
That is not what happens here and probably not good to happen anywhere else.
Also I would like to mention that while you were here you asked us to extend your stay more and we refused. We did that because you were not a positive participant.
