Many, especially women, often say "Ocha suru? " when we'd like to take a break while being outside for shopping or so. Then we go the place to drink and take a rest. The expression "Ocha suru?" literally means "Shall we do tea?". But it isn't always the case. Some order coffee or juice.... not tea although we say "do tea". I had never ever thought this is interesting until a friend of mine pointed it out.
For Japanese, "tea" doesn't mean only drink to quench our thirst. It implies the time to relax. Whether you're a tea-lover or not, whether you prefer coffee or not, let's do tea!
