Our Rabbis have taught: When Israel is in trouble and one of them separates himself from them, then the two ministering angels who accompany every man come and place their hands upon his head and say, ‘So-and-so who separated himself from the community shall not behold the consolation of the community’. Another [Baraitha] taught: When the community is in trouble let not a man say, ‘I will go to my house and I will eat and drink and all will be well with me’.

there is that fruitstock festival in Regents Park today, and I really want to go. But bad news from Israel are coming. 10 soldiers were killed.
Should I go out for a nice day in the park while my peopole are suffering???
