    a 40 foot drop, just so she can be a youtube sensation.

    My apple ipad is now broken and she has 83 views.
    I know this is completely off topic but I had to share it with someone!

  4. Hey just wanted to give you a quick heads up and
    let you know a few of the pictures aren’t loading
    properly. I’m not sure why but I think its a linking issue.
    I’ve tried it in two different internet browsers and both
    show the same outcome.

    his/her mind thjat how a user caan be aware of it. Therefore that’s why this piece
    of writinmg is great. Thanks!
