  1. En passant du « verlan » à « la langue des oiseaux » je remercie notre Chasse-clou d’avoir fait vagabonder ma curiosité vers un auteur et que je ne connaissais pas mais que je vais découvrir !

  2. Cái vụ đi miền Trung, Tây Nguyên này là có phần em đấy anh Tuấn nhé, đăng ký xếp gạch giữ chỗ đầu tiên đấy.

  3. I too am disabled but my child chasing day are over. (5 children, 14 grandchildren and now working on greats). You are right..you learn to adapt! I have so many projects I’m working on I get overwhelmed. My darling husband has moderate to severe Alzheimer’s so it’s like having a 5 year old around all the time. He does keep ,me busy. I’m enjoying this project and reading everyone’s comments is so fun.

  4. First of all, Id like to introduce myself. My name is Dennis Prickstick and I am a full time online money maker. I own a lot of seo software: ScrapeBox, ScrapeJet, GSA, SenukeX, Ultimate Demon, Article Marketing Robot and a lot of other including the old but still good Xrumer. If you own any of this tool you know that the key to dominate search engines like Google is the seo lists that gives you high authority backlinks.
