I'm back from holidays, let's meet and catch up.
*Перевод: Я вернулся из отпуска, давай встретимся и поболтаем (узнаем новости).*
Explanation: "Catch up" means to talk to someone you haven't seen for a while and find out what they have been doing. It fits perfectly in the context of returning from holidays and wanting to reconnect.
