I've been a carer for 12+ years and have 'kissed' one patient on the cheek whilst we had a hug. I had cared for her for years, we had built a great rapport. She was on her death bed and unfortunately passed away a few hours after.
Even still sometimes I question if I was completely inappropriate in that moment, so for Paul to just be throwing them around to anyone and everyone gives me the absolute creeps!
If that was my family member I would be questioning him tbh
