True story:
Once in high school, my first "serious boyfriend" cheated on me. When I found out, we broke up. The following weeks he tried to get me back, by giving me a series of notes. I got so annoyed with his constant note writing, that eventually, I just started correcting all his grammar and spelling errors and handing them back.
Be my girlfriend, please.
I have done that to people before. It is
sooooooooo excellent to see the look on their face when they realize you've taken the hateful bile that they have spewed onto paper and created a coherent letter that makes them not look like a douche.
On the topic of sending 'no thanks' and acknowledging strangers:
I think if someone sends the message saying "hey, whats up" and there is no response, whatever, who cares, its like real life, you say that to someone in person mostly they'll say, "hey not much, you?" as they're walking by and not even wait for your response.
But when you take the time to write out a pretty sizable message to someone, showing that you took time out of your day to actually read what they have written rather than look at the pictures and go 'she hot, i wana fuk her' I think that can deserve a response. Of course, I'm a grammar nazi a lot so I don't often respond to people who TALK LIKE THIS, LiKe ThIs, or lik dis. But if they seem like they're at least a little smart, I'll talk to them.
The truth of the matter is that on those sites, most of the girls are getting 10x more email than the guys. That's just how it works, the guys will send out bunches of emails and hope that just one or two of the girls respond, because most of them don't respond. Hell, I've even been of the mindset that even if it doesn't look like we could have a relationship, lets at least be friends, the Phoenix Valley is a damn big place, you never know what part of town you might end up in when you need a friend. I could have probably not gone on so long with this, but WHATEVER DUDE, JACE IS TIRED OF NEVER HAVING RELATIONSHIPS OKAY.
tl;dr: Jace is disgusted with how online dating works.
