Me and my girlfriend's pillow talk about memory leaks

Me: **... So garbage collection is a means to stopping a memory leak from occuring
Gf: what 's a memory leak ?
Me: a memory leak is like when you want a pizza, and the guy gives you pizza. But you don't eat the pizza and you ask for another pizza. You keep doing this repeatedly. Until the pizza guy realizes what you're doing and decides to kill you. He then takes back all his pizzas
Gf: why would you do that though?
Me: Lazy ass programmers who don't clean up after themselves.
