I don't want to seem insensitive, but I'm thankful that there are folks who are brave enough to be vigilant about this despite their own lack of handicap (like me).
Kim and I have driven into many parking lots and Kim's always scanning to see if folks have the tags. It's just a disrespectful thing to do; parking in the handicap space when you don't have a tag.
So I'll begin with a sincere thank you for folks who are assertive enough to care.
Now, on the flip side, when engaging in a conflict with someone you don't know, you're always entering into a potential risk. You just can't know for sure. I'd hope that folks with handicaps could be strong enough to take the high road and thank the seemingly offensive ill advised, but trying to do the right thing type person. They are doing the best they can, and unlike folks who spend a lot of time here thinking and typing, many other people are not so articulate or PC (not that you need to be PC here).
I understand the annoyance. But, I'd take it as an inconvenience when compared to the potential good this person is likely to bring in the long run. One solid tactic is to not ever be defensive, thank the person for caring and encourage them to keep it up.
Robbie, I love the sticker.
It would be really nice to be able to put links in here
If I have included a bad link, google the word "Scholar", click link for "Google Scholar". Search for the name of the paper and author in Google Scholar.
