My son when he was young had a pair of cufflinks with his name on them. After wearing them every Shabbos & Yom Tov for over 2 years, one of them, once got lost when playing.
He was so upset, that the following time I was in Meah Shearim, I got smart, and ordered 2 pairs (4 pieces) of identical cufflinks, so even if he were to again loose a cufflink even twice, he would still have the matching cufflink.
This overcame the singles crisis, of-course coupled with Murphy’s law, that because of the 2nd pair, he has not lost even one from the first pair, in several years.
