I speak a few languages. One of them is Spanish. I speak it fluently (natively), but nobody guesses it because I'm white. I've always thought it's a great practical joke when I'm with someone who I've known for a little while and I've only spoken to them in English so far, and I pick up my phone and start speaking Spanish fluently, or start speaking to a cashier in Spanish. The look on their face is priceless! Usually they are really surprised and then I explain how I know Spanish.

My question is, would it be different if I did this to an SO? I thought it would be pretty funny to play the long con on them, and then maybe in a few months bust out the Spanish on some random occasion and see how they react. However, I saw on another post that someone lied about their middle name for a few months and people were saying YTA to her.

So, WIBTA if I did this? Is this essentially an enormous breach of trust?

RIGHT
