[Van Khanh]

Hi,

Please read:

1.With getting up early and travelling all day, we we exhausted by the evening.
2.With getting up early and travelling all day, we we exhausted in the evening.

Please tell me the difference in meaning btw: in the evening and by the evening in these 2 sentences?

Thanks
