Jared, this one's for you.

English, my first language.

"These are alternative forms of the past tense and past participle of the verb learn. Learnt is more common in British English, and learned in American English. There are a number of verbs of this type (burn, dream, kneel, lean, leap, spell, spill, spoil etc.). They are all irregular verbs, and this is a part of their irregularity."
- AskOxford.com

And this whole time I had to go back and change "learnt" to "learned" in my emails to you. Darn you. I was right about that past participle thing. I just didn't know that I was using the British version. Hah.

I hate this dual system thing. I have to think twice when I write words like "neighbor", "color", "favorite", "organize" (organise? That's stupid) etc.

I spelled (spelt?) them that way during spelling in elementary school and would get them incorrect. It made me SO mad!

The other words I have to think twice before saying are:

Flashlight - Torch
Shopping cart - Trolley
Wind shield - Wind screen
Parking lot - Car park

And YES I say "fortnight" and "shan't".

What's so funny about that?!
