That's the message of an ad posted in the local paper of an ultra-Orthodox Jewish community in Monsey, NY. You can read the whole ad below.
The ad, published in the March 1-8, 2012 edition of Community Connections, reads as follows:
To all Esteemed Donors and their Devoted Families:
Purim is a time of joy and merrymaking. Your homes are full of costumed adults and children who collect for various tzedaka [charity] causes. Please be aware that the laws of tznius [modesty] apply on Purim as well. Keep in mind that it is inappropriate for women and girls to mingle with the guests, especially when the mood is "Purim'dik."
Purim is a holy day, likened even to Yom Kippur. It is a day when our prayers are answered and people merit yeshuos. But in order to utilize the kedusha [sanctity or holiness] of this day we need Hashem's presence. The Chofetz Chaim zt"1 wrote: The Torah warns us that Hashem [God] will depart from us if there is a lack of tznius among Klal Yisroel [the Jewish community]. Conversely, when there is kedusha and tznius among us Hashem rests his Shechina[divine presence] in our midst.
Dear women and girls! Please don't think you'd be missing out on any fun if you stay in the inner rooms. Your reward will be eternal! If you must be present where the tzedaka collectors are received, please try not to be noticed or heard, and be especially careful not to laugh out loud. You'd be doing a tremendous favor to the chashuva tzedaka collectors, which may include esteemed Rabbonim, bnei Torah and innocent young bachurim [high-school-aged male students].
In the zechus [merit] of your tznius, may Klal Yisroel be blessed with Yiddish nachas [pride], parnassa [living/livelihood] and kol tuv.
Be proud like Esther Hamalka!
Translations are approximate; feel free to add or discuss in the comments. A call to the number listed at the bottom of the ad went straight to voicemail; I've left a request for comment but haven't received a reply. A spokesperson for Community Connections told me that the ad was placed by an individual, not an organization — she couldn't give me his name. However, a little digging reveals that this individual has posted the same ad before — it ran in Community Connections last year.
