I don't take online dating sites/apps very serious anymore. I've been burned a number of times and just really don't expect much.
If I mail you and don't get a response then I'll just move on. Silence is better than having a conversation with someone who gives 1-2 word responses.
If I've visited your profile, and you like what you see, then send me a message.
if my mailbox is full (it's getting there)
