I was NOT prepared for what I walked in on today with my little cousins

So I walked in on my two little cousins (both 2-3 years old, boy and girl) just casually pulling down their pants and COMPARING.

…pata hai aaj kya hua? My soul left my body.

I completely froze, didn't know whether to laugh, cry, or just run. Ended up awkwardly telling them to play in separate rooms and stood there questioning everything for 10 minutes. Nobody prepares you for this. Has anyone experienced this??
