You do not need a speech
Most people avoid ending things because they think they need a perfect explanation.
You do not. You need clarity and kindness.
A simple message is enough
Try: I enjoyed talking, but I do not think this is the right fit for me. Wishing you the best.
Short, clear, respectful. That is it.
Do not leave the door cracked
If you are ending it, end it. Mixed signals create confusion and resentment.
Respect is not just how you start. It is how you finish too.
How Found solves this
Found is designed to encourage follow through and respectful endings instead of ghosting.
When standards are built into the culture, clarity becomes normal.
