>I'm just doing it to be more in character
You aren't even attempting to match that character's voice, you use the same one no matter what avatar you are

> IC and OOC separation 
You only ever talk about yourself, why would that character be talking about you? You never talk IC it's all fucking OOC. 

Just accept that the voice you think is cute is actually very annoying and grating but that doesn't mean I hate you, I don't want to mute you because I still want to talk to you, you're still a perfectly fucking good person the fake voice you use is horrific though.
