My dad had a stroke and was also diagnosed with Dementia , effecting his memory and bodily functions . He has a female friend who visits at times but has been showing inappropriate behavior , such as kissing him on the lips , rubbing his leg near the groin and sitting on his lap . She likes to just stop by unannounced but if she does call first usually late by hours , she stays to long , last visit 4hr ...my dad was tired and became agitated. I have asked her not to do this to please keep her visits short and just l act like a friend but she continues. So i feel this does him harm by leading him on and makes him emotionally difficult to handle , any suggestions how to approach her again ? Or am i being over protective?
