Another OKCupid question: how long is too long to wait before replying to messages? I've received a few actually nice messages from people who seem interesting, but I've been both swamped with grad school and also, frankly, a little nervous about the whole talking to strangers thing. It's been maybe between 1-2 weeks since the first messages, and I'm thinking about replying but now it feels a little awkwardly delayed. Thoughts?
