My 'lil' sister and an eyeliner

A couple days ago, when I passed by my 'lil' sister, I realized that there's something weird under her eyes. I glanced at her and said "did you put on an eyeliner under your eyes??" She looked at me and quickly answered - "uhm, did I?" Having caught her in a lie I continued the ruse - "what are the black marks under your eyes?" I added, then pointed my finger right up to her eyes before yelling "Gotcha!!!"  Yet all my 'lil' sis replied was... "maybe," giggled and walked away. LOL, kids! XD

Hey Za, nice story haha, berapa umur dia?
Great work with the story, this is how I would write it to sound a little more natural :)

My lil sister and an eyeliner

A couple of days ago, when I passed as I was passing by my lil sister, I realized/noticed that there's something weird on her. I glanced at her and said "did you put on an eyeliner under your eyes??" she answered quickly "uhm, did I?". I replied, "yeah I guess, what's that are those black marks under your eyes?" I added, and then pointed my finger to her eyes. gotcha! and then she just said "maybe.. hihihih" giggling, and then she left me. LOL, kids! XD
