Dandelions

I have a single minded mission to eradicate dandelions from our yard. I take my forked weeding tool and everyday circle the lawn and gardens looking for dandelions. I must have learned this from my mother. I remember when we were kids she used to pay us 1 cent for every hundred dandelion flowers we picked. I learned that these plants are perenials. I also learned that they can regrow from the taproot so it is possible that I am not eradicating them. I do know that I can't see any dandelions in my lawn and garden. I even pull them from the adjacent areas of the neighbors lawn. Do you think this is a fetish?
