Maybe we could just say "SHE/HE JUST LEFT."

A couple is an example of a collective noun. In your example, sentence 1 is correct. It is somewhat similar to the "team". You can’t have a team without individual members; even so, we discuss a team as a single entity. But the collective nouns can have a PLURAL verb depending on a situation. example: There are three teenagers in the living room . Are they all doing the same thing at once? Not likely! One is watching TV intently. Another is reading a book. The third has one eye on his computer. There is a single group of teenagers, but the members of the group are doing different things. Members of collective nouns can act the same way, as individuals doing their own thing. When members of a collective noun act as individuals, that collective noun is plural and must be paired with plural pronouns and plural verbs. So in your example, the couple was doing the same thing at once which was "HEADING". hope this one helps you.

Hi Maki! This is a good question especially if you are learning present perfect tense for the first time. Present perfect tense talks about your life experiences and to do this, we use "ever" and "never". Never means "at no time" In your example, you can have these following sentences; 1. I used to eat this before. 2. I have never eaten it since last month. 3. I have never eaten it for a month. 4. I haven't ever eaten it fo a month or since last month. hope this really helps you.
