From the time I was born until last monday I was tongue tied, I got a Lingual Frenectomy(where they cut the frenulum, the skin that holds your tongue down). It didn't affect my speaking at all, but it wasn't really possible for me to roll my r's still. Now that im physically capable of it(or I should be anyways) I still can't seem to do it. I know a small portion of Russian speakers can't do it, and ill probally be understandable, but does it make you seem well....odd? For example you guys have all talked to somone with a lisp before im sure, they are considerd to have a speech impediment, does your ability to roll your r's sorta place you as the "weird guy" i guess.
