my first time seeing of a snake

yes in 2004 when i was in lower kindergarten and in Falakata i was looking at the empty space behind my grandpa's house and then my youngest aunt who was 12 that time told me that there is a snake there. i didnt know what a snake meant or looked like and the thought the white plastic bag on the ground was a snake and then i asked whether the plastic bag is snake or what she said no and she kept showing me but i couldnt see anything
