b is big on privacy... since we've introduced him to the concept and he's been slowly exploring it!! we taught him to say that so he can straight up tell caregivers when he needs alone time. instead of saying "go away!" he would say "excuse me, may i have privacy please." we thought it was more polite!!
but he's since extended that courtesy to us and would go around opening our bathroom or shower door, poke his head in to confirm if we need privacy and shut the door after him after he declares "he/she need privacy!!!" lol!
hope he always finds family that will love him and think that, though weird, he is rather amusing!
