Почти всю зиму он провёл в одном из подмосковных домов творчества и там на людях немножко успокоился, пришел в себя. (Н. Рыленков, Недопетая песня) — For most of the winter he had stayed at an out-of-town rest home where he had found some peace of mind being among so many people.

Вообще на людях он был совсем не тот, что наедине с Луниным. (Н. Чуковский, Балтийское небо) — Altogether he was quite another man in company from what he was alone with Lunin.

На людях [Захар] был весел, с постоянной усмешкой в глазах, дома же ни с кем не разговаривал, старался поесть от семьи отдельно. (П. Проскурин, Судьба) — In the presence of others he was very cheerful, with a constant smile in his eyes, while at home he spoke to no one and even took his meals separately from his family.
