Question time!

Salam aleikum, all. Sorry I've be incommunicado for so long! I'm popping in to ask a question. Question: How many of my (non-Muslim) friends here would be willing to attend and observe a Friday prayer service, go to a class on Islam, or some other activity (festival, interfaith event, etc) at a mosque? If not, why? If you have been to such an event in the past, but would not be willing to go again, why wouldn't you? Share this with your friends! I want as many answers from as many people as possible.
