He was mekabel everyone besever panim yafos.

When you didn’t return a smile he didn’t let you go until you smiled.

Always had something nice to say. Always had a joke or גלייך ווערטול to uplift your mood.

Would joke about his own pain.

I observed him at a Shiva tirelessly working to get a smile out of one of the avelim.

As a kohen he would also give you a big heartfelt Bracha באהבה

True to his nickname אהרון כהן גדול
