I don't understand your conversation. What do you mean by two birds with one stone.

Oh sorry for confusion. What I mean is your photo has 2 kinds of glass in it. The drinking glasses and the table top which is also made of glass. So since in one photo you have 2 different kinds of glasses I said it is like hitting 2 birds with one stone. It is an expression actually.

Oh I see, I don't understand your thoughts,it's my fault. Thank you for appreciating my post
