Yup my dad's mom shakes because she used to drink a handle of Jim Beam every couple days. She adopted my dad so it isn't the missing link to my tremor. Just a sad old lady with alzheimers and addiction.

Emily- My mom works with someone like your co-worker. Now she wonders but doesn't ask him either. It is the fine line of being concerned or just making them feel so small because you noticed. I would prefer 9/10 times that no one says a word.
