I married a foreigner and for a few years when she was learning my native tongue, my own vocabulary and ease of expressing my self deteriorated noticeably. Even when speaking to others. This was quite a few years ago. I'm back on track but it was a frustrating experience. Similarly I find myself speaking better English when "guided" by an American or English person. It's weird... If someone else speaks broken English, I will too.
