Question:
Is it permitted to go out to dinner with a friend (or friends) during the year of aveilus?
Answer:
Hello,
In general a person in the year of aveilus does not eat what is called seudas merius, (a socializing meal) outside of his own home. If there are specific circumstances, that should be discussed with one’s Rov.
Best wishes
