It's not good though to avoid it. You will never get any better if you do that. It's best to push through sometimes. My first last name starts with B and D and I block like a mofo sometimes. It's frustrating as hell I know but the more I do it the easier it is, or maybe it's just easier to not GAF about what other people think. The other day I was at a Wendys drive through and I couldn't get some word out and I hear the girl mumble under her breath "oh my goooddddd". Pissed me off to no end lol I was like uuuuhhhh am I bothering you? What the hell??? Should I just fucking leave? Older I get though, the less I care...these last few days have been real hard speech wise for me for some reason...annoying. Have a good day...and you gotta face your fears!
