This Is How Aliens Are Going To Destroy Us

Fantasy time!
Time to relax your mind and squeeze the absurdity out of you.
But remember, pal. For that even in absurdity there might lie the truth to ponder.

I have been thinking about how humans can be easily destroyed by aliens in the future, and this is what I've managed to come up with.

An alien comes down to Earth for a vacation and stops at a gifts shop.
This is the conversation.

Alien : Kreeeeeeet..(it can't speak human)
Father : Stop playing with your phone, Aqil. (busy wrapping up a present)
Son : I'm not playing with my phone, dad.

Alien : ...?? Kreeeet..?
Father : For God's sake, Aqil, can you please stop playing with your phone? Can you help cleaning up the place or something?
Son : I'm not playing with my phone, dad! And the place is already clean.

Alien : Kreeet? Kreeeeet..!! (angered by the fact that nobody is serving him)
Father : Okay! I've had enough! (he stands up, walks towards his son, takes the mobile phone off the son, and throws it out of the place)
Son : Dad! What's wrong with you?? What did you do that for??!
Father : I'm tired of you, okay? Such a bonehead and all you do is play! No wonder your mom left you in the first place!
Son : My mom didn't leave me! She left you! You stupid jerk! The only thing you know how to do is to sculpt things and sell them! That is all!!
Alien : Kreee...? (stupefied)

The son leaves the place and never comes back.
The alien is too small for them to notice, and even if they do, to them 'he' will look more like one of the sculptures the father made rather than a 'person'.

Alien : Kreeeet..! (poor service!)
