Do you talk to your self?

I talk a lot to myself lol, happy to see this thread as it makes me feel more normal.
Sometimes I have long 20+ minute discussions with myself just to see a stranger walk by (Yes I don't only talk to myself at home uuu...) and at those moments I just shut up and pick up my phone & hope they didn't hear anything.
Really awkward and I have tried to stop doing it but it actually helps me remember a lot of things & it's a nice time waster e.e
