I just returned from a 2-week visit with my DF and his wife. She has had Alzheimers for ~8 years. I believe she's in the middle stage right now and starting to experience behaviors that are more difficult for my dad to handle. One of those is the inappropriate touching of strangers. They are a very social couple and still enjoy going out. About half-way through a meal, show, etc...she will get up and start conversing with strangers. She's very effusive and then she starts touching them. Most people pick up on what's going on and humor her. However, some people are clearly bothered and irritated. I made it very clear to her that she has to respect my personal space and I always remove her hands when she starts on me. I think my father is at the point of just giving in to her because she gets very crude, nasty and loud when he tells her to stop bothering others. Any advice?
