Beautiful errors: praten met of tegen iemand

You can learn from errors, especially when the errors are beautiful and/or hilarious. This way, it’s easier not to make these errors (again).

“Ik heb gezellig tegen haar gepraat.”

This should be:

“Ik heb met haar gepraat.”

a dialogue, in both directions

Because:

praten / spreken tegen

a monologue, without answer
