Sorry, my bad. ;-(
Look it’s ok with me but if you want to improve at all, you’re going to have to place your tongue between your molars and bite down with all the force you can withstand or until your tongue becomes all swollen and bloody and it’s hard to talk; whichever comes first. Then you can proceed to talk ebonics (no one will know that you’ve never taken an actual course in it because it will ‘sound’ like you have)
