I saw a nice story about Rb Wolbe z”l in the mishpacha some time ago. His son (wearing army uniform and not yeshivish) was davening minchah with him, someone (nastily) walked up to his son and said to him – do you think your father is happy with the way you turned out. His son was upset by this so walked up to Rb Wolbe after minchah and said ‘ Abba, are you happy with the way I turned out?’
Rb Wolbe didn’t answer. They walked home for 10 minutes and then Rb Wolbe turned round to his and said ‘Yes, I am happy with the way you turned out’. He asked why didn’t you say that before. Rb Wolbe said – if I had said that when you asked me you would have thought I was just saying yes.
