Are there any texts or commentators which discuss the idea of Rosh Hashanah being a day of friendliness?
The Artscroll/Stone on Bamidbar 23:22 follows Rashi's understanding (Bamidbar 23:21) of "utru'at" as from the language of re'ut (though other meforshim stick with "trumpet blast"). If one can understand tru'ah here as neighborliness, this might add a dimension to the meaning of Rosh Hashanah as Yom T'ru'ah.
Is anyone familiar with sources which explore this possibility?
