I'm not assuming. I've drunk texted people before and I know what's fake and what's real. You very clearly don't, it's something you have to experience before you understand.
Chances are your 'older friends' are not first timers, like espio. And it was hardly 'incomprehensible gibberish', forget outta here with that weak ass stuff, it was practically just a few spelling errors in a run-on sentence.
Yes, you are assuming. I have experienced plenty, I have online friends who drink and have talked to my dad on several occasions when he had been pretty wasted over the phone, and over text too. Again, stop assuming.
There wasn't any proof to anything that espio did, it's really easy to 'act' wasted on the internet. You realize 80 percent of people in OP's thread that he linked were calling espio a bullstuffter right?
