This actually happened.
A good author friend of mine has a newly released book and I wanted to give my support and thoughts about it.
I sent her a message using my phone, “I believe your book should be on the Self Imodium section. So that people will know what it can be used for.”
Her shocked reply, “you think my book is good for constipated for people?
My confused and embarrassed reply, “What?!! I meant SELF-IMPROVEMENT!”
Thankfully our friendship survived no thanks to you auto-correct!
