Some are only for men to perform.
Some are more geared towards the women,
I am finding more and more though, that in the desire for limmud Torah, certain mitzvohs that are not gender specific, are being relegated to the "bittul zman" pile. Why? I'm not sure.
Bais Yaakov schools around the country send their female students out to hospitals and nursing homes to visit the elderly and infirm. Yet many men languish in these facilities and in their homes, craving a young man's face - wishing a yeshiva boy would come and learn with them or merely talk to them. But the boys never come. It's "bittul zman".
Chessed in general, has become in the Yeshiva system, something to be thought of as a waste of time at worst or a "girls' mitzvah" at best. The Yeshivish crowd on the whole is far too busy learning to take time out and actually perform some of the mitzvohs that they learn about.
Is the Torah not meant to be a blueprint by which we go out and LIVE our lives? Why don't the Yeshivos stress chessed for boys as much as for girls?
