Texted version of popular expressions:

Talk (my/your/his/her/our/their) ears off: write (my/your/his/her/our/their) eyes off.

I'm all ears: I'm all eyes.

I'm listening: I'm reading.

I'm glad to hear that: I'm glad to read that.

Look at me straight in the eyes: Look at me straight in the eye-con.

I'll keep adding more as time goes by :)
