I went to a meeting yesterday that dealt with some serious issues, but there were a few light moments. Most of the attendees were bilingual, although the principals spoke primarily Spanish. There was a translator for the few of us English-only speakers.
"Rosa" did a great job, but the difficulty of thinking in two languages simultaneously was apparent when she began explaining something to us in Spanish. The best moment came, though, when two parties were speaking and Rosa began explaining their conversation, not noticing that they were already speaking English! We really did laugh out loud. ;-)
