Just wondering when hugs and kisses turned into x’s and o’s. Searched the archives, but didn’t find anything. If this has already been posted and answered, just post a link, thanks. Thanks to all who answer.

I think the X looks like a kiss feels (when you pucker up for Gramma), and the O is wrapping around someone with a hug.
Not from the SDMB archives, but here’s some speculation.
