The story. (courtesy of "Tiferes Yisroel Ruzhin")
Are all the facts listed here correct? Anybody? I did not know that the Horenstein to whom's levaya the Rebbe went to the East Side was Mendel's brother. I also think that the Rebbe was so concerned about whether or not the Boyaner Rebbe - or Chassidim, rather - allowed for their Rebbe to be touched, shows his concern and respect for the minhogim of other kreizen, as well as the privacy of another human being - if I may so myself.
