I personally always find my self rather talking to my self! It helps me think because I am basically thinking out loud! XD

Humming and then singing what I must do always is something to suffice in the situation as well, in regards to the matter of course. XD

So my vote is yes, I do speak out loud, and if I am by myself to! XD

Folks tend to laugh at me at times, I used to always talk to my self when I worked as a librarian, and heck a lot of others did the same as well. When they laughed it wasn't mocking or laughing at me, it was laughing with me because like I just said. Others as well also do it! Many folks that I've encountered in my day talk out loud! XD

Heck I am doing it right now as I type this! XD

Errday nigga

i talk to all my many selves

I often think out loud when I'm planning something

I realized when crafting I talk to myself a lot.

I also make sound effects when I drive.

lol don't we all. I only do it when in my slow cars just to make it feel more exciting hah

only when I'm high

Do you know what came to mind when I first saw this thread? This segment from RAW. Funny moment.

ya all the time

i say things out loud all the time and even respond to myself with the answer at work!

i'll be like, "hmm.. what do i need? oh yeah! i need 3 sweet teas, a Dr. Pepper and 2 waters! "

"oh and i need to drop rolls of at table 32! "
