carole, on this one, let it go, this is a battle you cannot win. she's 15, you gave her good values, standards and ethics. save your energy, and develop stratagy for the much larger battles ahead. few things are as difficult to deal with as an aggrieved teenaged daughter trying to emotionally seperate from her mother. keep the bottles of sunblock around, and in your purse, let her see you using it, be the example, not the fussing at her voice and she's much more likely to come around. kindest regards
