Sorry i feel really stupid that i don't get it

Manal, please don't ever feel "stupid" for not understanding something.  We, as human beings, are learning something new, every day of our lives.  There are no stupid questions, but there can definitely be difficult answers, that take us a bit to understand.   It's a normal part of life, and pertains to everyone.   :hug

Thanks a lot Mustho, your post is very informative.

Thanks Danielle so much, you are always very supportive
