Luckily when Mrs. Gevano said that, Ramon was quite far from them. So, it was safe for Hailee to assume that the man didn't hear what Mrs. Gevano said just now.
Meanwhile, Mrs. Gevano also knew that Ramon couldn't hear them, so she continued her small talk.
"If this had been the marriage of the two of you, your mother would have been very happy, because after all this was the wedding we both wanted," Mrs. Gevano kept saying anything and everything as if she had forgotten the fact that Hailee had married another man and today was her son's wedding to a woman of his own choosing. "I know your mother very well."
On the other hand, when she heard that, Hailee politely withdrew her hand from Mrs. Gevano and while still smiling, she replied to those words.
