Send me any message you would like.
If you want me to write back, I need two things from you.
First, show off a bit. Tickly my fancy. I respond to less than 10% of the messages I get. I like flattery, I like when we have things in common, but I will be more intrigued by why you are inteseesting, rather than why you are interested in me.
Second, and even more important, you need to include your contact info.
