Or they walk up to you later and ask if you understood that math question that morning and you are like, "uhm.I wasn't here for that," and they are just like "really? I didn't even realize that you were gone." ^^So sad but so true
This is the part in The Lion King where Zazu mentions Simba & Nala getting married, and it's just before "I Just Can't Wait to be King". As cubs, Simba and Nala just want to stay friends and that's it.
