fish on fridays

me and dad have just come back from a drive and we past a fish shop, and i observed that it was open

dad: who buys fish on sunday
me: people who forgot to eat it on a friday.

after a moment of thought dad points out that we ate fish on friday, and this being unusual for me I said 'you did'

dad: you did too

i thought for a second and realised i made tuna filos on friday and i ate a couple

me: OH MY GOD! I AM TURNING INTO A CATHOLIC!

dad: *laughs*
