Janet, Watch your self talk. Are you referring to yourself when saying "pest"? Or did a cockroach just walk into your view. I think you are adding to my understanding of PD (?) by sharing different research and intuition ideas. Keep posting! Patricia 61/3 1/2 yrs p.s. I passed my drivers liscence renewal, as long as you can see with one eye you're in the drivers seat. Can I drive anyone somewhere?
