Onions have layers, ogres have layers..
donkey says “really really” to shrek when reassuring him that he likes him, shrek later says “really really” to donkey when reassuring him that he’ll help him cross the bridge to fiona’s castle, and then shrek says “really really” to fiona when he tells her he loves her
in conclusion, donkey taught shrek to love and be loved
thanks for coming to my ted talk.
