Did you have older siblings growing up ? And if so, what sort of stuff things did they do that make you laugh now ?
My sister is 12 years older than me and we shared a bedroom when I was about five. She'd lay her head on my stomach and then make me giggle t hen say " pillow ! Be still " ! Which would make me laugh !
Or take my wrists and make me slap my face & say " Marji, stop hitting yourself " !
My brothers on the other hand played dirty, and the first time I swore they carried me in to my mom & told on me. I got my mouth washed out with soap ! : p
