Another reason to give soba was because the shape of the soba noodle, which is really long, symbolizes hope for a long friendship, a lot like toshikoshi soba for New Years, and maybe it is a play on the word itself, soba (ni), since soba ni means close by. Like this pun: Osoba ni suenagaku otsukiai wo yoroshiku. Which means best regards for many years of friendship by your side.
