You really have no idea whether this person will be the right one for you, so don’t try to flatter them with a lot of compliments, or be amazed at everything they say. You don’t even have to agree with them!
Instead ask yourself: “Who is he/she? Do we have common values, interests, and aspirations? Do they have a good sense of humour? Are they kind, and worth my time, energy, and commitment?”
Be on time. Too early and you’ll wait and get nervous (everyone does). Being late forces the other person to wait and get nervous.
Put your phone away. You need to be ‘present’ not distracted. Save couple selfies for when you are in a relationship.
People have different levels of personal space. Try to find the middle ground between an ‘awkward distance’ and ‘touching’. If you treat someone like a distant stranger they will feel like that. If someone moves back, you are too close.
Listen. This involves speaking less and listening more. Letting them do most of the talking takes the pressure off you.
Silence has a purpose. Pauses give people time to think about what was said and process it. You don’t have to fill every gap with words. In fact, people who are comfortable together are also comfortable with shared silent time for thinking.
