hello,everyone:
Thank you for your attending to the gathering this weekend.
I am very glad to be the host this time. Although the article I chose
is a little difficult for most our members. I think it is my fault. Because
the article in my work field is very simple. I do not concern other people's
background difference. So I will choose more common article next time , if
I were the host next time. So far, I still thank you for everyone coming.
Thank you.
sincerely,
David
