For example , one hebephrenic man used to annoy me, month after month , by saying , whenever I got up to leave and made my fairly steoreotyped comment that I would be seeing him on the following day , or whenever, "You 're welcome", in a notably condescending fashion - as though it were his due for me to thank him for the privilege of spending the hour with him, and he were thus pointing up my failure to utter a humbly grateful , "thank you " to him at the end of each session .
