Input: Text: she thought that jackie chan was just a fictional cartoon character until we watched rush hour.

she thought that spam was a type of fish because they sell it in a fish and chip shop and questioned my ethics when using it as fishing bait.

she never knew that pickles and cucumbers are the same thing...

and she is currently sat here playing with my foreskin trying to figure out how it actually "works". "it serves no purpose".

she is 18. if i base this relationship on mental age and iq, i feel like a paedophile.

TIFU when I realised I've been dating a retard for 2 and a half years.
