It all depends.
My manners are quite different from everyone elses around here. To me, manners also mean patience and personal space and very few people here actually know what patience and personal space is.
How I respond is usually depends on how I feel. Usually I just ignore them and walk away returning later to try to do what I need to do, and others?
Well, I am human.
99% of the time I just ignore people and like my mama always said, they will go away.
But... the other 1% of the time...
If they get too close and I've asked them to respect the space- well that doesn't happen. I actually wait and wait and wait and wait for the space I need to be emptied. It has gotten to the point where the cleaning women put bets to see how long I have to wait for the lift each morning. It is hilarious as all get out when I sit here and think about it, but while I stand there waiting and waiting, I begin to wonder where does patience end and stubbornness begin?
If I am at the store buying groceries, and people walk over and reach into my cart pawing through my groceries, I will reach into their purses or wallets and try to aim for their wallets.
When people stare at me as I walk through the city, I usually ignore them, but there are days when it just.... gets to me and I am human. I take out my camera and start taking pictures of them. But I have to admit, those days when cyclists ride into a wall or a person or a car hits another car because they were watching me... I do get a little hop skip and a jump on the insides laughing at them.
There are so many others... I try to have a sense of humour about it... but when you call in asking for the balance on your telephone and they start to lecture you about how many international messages you sent last month... I just get a little irate that my personal life is any of their business.
