I feel old pretty much every day that I continue to rp anymore. Because back when I started I took more than 48 hours to write up an application (I still do, actually), I didn't create a journal until the application was accepted because journal hogging was considered rude, I didn't steal icons (I either made my own or put credit somewhere), people weren't ragging non-stop all passive aggressively in vent communities about their RP partners having priorities outside of rp (some of us are mid 30s and older and have jobs, spouses, kids and stuff... good lord)... and the flaking.
And the drama.
I sort of miss early 2000s rp sometimes. At the same time, I have a happy niche of people the have been playing just as long and we have our happy little hidey-hole of rp. Things are just... weird out there.
Don't feel bad, I can't keep up with the slang either.
