Two people doing something together

There are words like "meeting", "gathering" or "get-together" that describe some people coming together for a certain time, for doing certain things together.

Those words may or may not imply that the people getting together are a group (i.e. 3 or more people) -- a meeting can be between two people, but I'd assume that a gathering is typically understood to mean a whole group of people.

Either case, is there any expression or preferebly a single word which indicates that it's exactly two people getting together for some activity?

Words that are typically used for an appointment between two people -- like date or rendezvous -- usually have a romantic connotation. I'm basically looking for a more neutral equivalent.

Solution 1:

Tête–à–tête is sometimes used for a meeting of two people. It connotes privacy (i.e., the conversation thereat is intended to be private).

Solution 2:

I feel like the simplest answer is partnering. While it can be used to include more than 2 people, it is generally understood to be between two people unless in a business context.

Partner: a person who shares or is associated with another in some action or endeavor; sharer; associate.

Example: Joe and Harriet are partnering to solve global warming.

Solution 3:

In IT, pair programming is a common term. It indicates two people sitting down in front of a computer, where one writes code and the other tries to find any possible mistakes as each line is written.

So you can consider "pair up".

to form a pair, or to make two people form a pair
