I don't know whether this is wrong, but when our sensei was away our sempai pointed out to us that sensei always bangs his shinai on the ground and that this is verry wrong (Bad shinai ettiquet (sp?)). nobody dares speak to sensei about this though, as he is quite a scary man. he also never speaks to us new starters, only the senior students, never jokes, smiles or asks us if we have any questiones . Is the shinai banging wrong? Are most sensei's this scary? Help is needed.....PLEASE!!!!
