Find TD Value

Find TD Value

I have a table with an ID of #MyTable and every row in the table has one column with a class of .tdSize and another column with the class of .MyCheckBox that contains a checkbox.  When the checkbox is clicked, I would like to get the html of the .tdSize just for the row where I clicked on the checkbox. 

The following gives me every rows .tdSize.  How do I ony get the row where I clicked on the checkbox ?

Thanks

 $(document).ready(function () {

            $('.MyCheckBox').change(function () {
                //if (this.checked) {
              $(this).closest(".tdSize")
                $('#MyTable tr').each(function () {
                    var size = $(this).find(".tdSize").html();
                    alert(size);
          
            });
        });
