Our daughter and her husband, who are both very socially aware, have asked us to give them a "Toilet twinning" present, which my wife and I are very pleased to do (having two ourselves). It is a good gift to give to those who do not really need any more material presents for their home or personal use as it funds the provision of sanitary facilities in countries where such basic requirements are lacking. It raises the standard of hygiene and toilet privacy (particularly important to women in rural communities). If you would be interested in making a similar gift to someone you know, the means of doing so are very easy to find using any search engine.
