If you're on an online dating website and someone reaches out to you that you're not attracted to, Galanes says to be considerate. "If someone initiates a chat with you online, or sends you a message, respond as politely as you would at a bar or a bus stop," he writes. "If this person goes so far as asking you out – even though she has the audacity to not be your cup of tea – how about a simple 'No, thanks'? Don't ignore her messages."
