The choice is in his hands.
He has the possibility to choose.
(Rabbi Yehuda holds that one should definitively go to his teacher, even though the second is a sage, and the choice is not in his hand to go to whichever place he desires. However, the sages do not believe so, for sometimes a person prefers to meet his friend before meeting his teacher — commentary on the Mishnah by Maimonides, Tractate Eruvin 3:5, and similarly: 'From every place the choice is in your hand; whatever is pleasing in your eyes is pleasing in mine' — Agnon, 'Ad Hena,' The Garment, 246.)
