I am a little confused about the use of la journée and le soir in this text. 'During the day' (Pendant la journée) is feminine - I understand this as she is discussing a length of time rather than a specific point in time. I don't understand why 'in the evening' (le soir) is not 'la soirée' - what distinguishes these two statements to make the switch from feminine to masculine? Is it the preceding "during" and "in"?
Thanks in advance!
