I used to pretend that I was someone else to my kid sister (9 years younger than me). I used to go into the bathroom and tell her that he (can’t remember the name) would come in through the window and I would go out (without her seeing of course). I used to slick my hair back and talk funny. She used to believe me (she was very young!). I’d talk to her for a while then leave. I would then come out of the bathroom as myself. Pretty weird, huh? She still gets a kick out of it now when we talk of it (I’m 40 now!).
