A colleague’s son is having a Bar Mitzvah in a non-Orthodox setting. The son went to Hebrew school, and the father has shown some interest in Yiddishkeit. You’re invited and can’t make it to the party, but would like to purchase a gift. Do you give:
1) A non-religious gift
2) A religious article such as a pushka or a menora
3) An english sefer on a Torah topic
If you opt for choice 3), what sefer would you give.
