We should not get confused 'sometime' with 'sometimes'
Sometime means any time in the near future. Sometimes means occasionally.
Sometimes: I go to the shopping mall sometimes. It answers the question, how often?
Sometime: You can meet me sometime in the evening. It answers the question, when?
Sometimes, people prefer watching movies at home than going to the cinema hall.
Bangalore has a moderate climate, but sometimes it gets very hot in summer.
Why don't we meet up sometime?
I would like to meet you sometime, but I don't have time this week.
