It's fascinating how many people on here confuse language exchange with a game of throwing messages at a wall to see what sticks. If you start a conversation, have the basic courtesy to see it through or at least give a farewell. Vanishing mid-conversation isn't a sign of you having 'too many options'; it's just a sign of poor etiquette and a complete waste of my time and yours. I am not here to be another option in your roster. If you lack the attention span or the respect for a sustained conversation, do us both a favor and keep scrolling!
