How I do reverse particle

[Alio Reaper]

I was trying to make a particle effect that is a typer that grow whenever I talk in local chat if I stop talk in local chat and it'll go shrink back to my own avatar, but problem is I can't figure out how to do reverse it? I can't find any example of this, so I just decide to ask for help on this forum.

Set the target for the particles to the generator itself, by setting it equal to llGetKey().
