This woman sounds like a *****. Sorry for being blunt but she sounds like someone who ahs nothing better to do than cause problems were there really are none. As for her husband, have you spoken to him? You're taking her word for what he thinks and has said and in my experience when someone a immature and pathetic as her uses someone else as her excuse its because she's looking for an excuse.

Matey, I miss people all the time as I walk with my face facing the ground and I'm often "on a mission" running from one job/errand to another - I have no freakin idea who I'm walking past and frankly time had taught me not to care. I live in a relatively small rural town and I even have friends who jump out in front of me and yell things like "Hey don't you ignore me" (being funny) and then we have a laugh about it because they know how I am and how much crap I have to get through in a day.

Don't take it personally, this woman just sounds like a person you ant as much distance from as possible.
