Lmao you don't have to. But always remember they're people out there that have worse things than what we have. We always thought that the older we get the mature we will get, but that wasn't what it turned out to be. I wish you good luck on your interview and I hope you get it. 1) Walk in with confidence 2) Tell them you have a speech impediment. 3) Whatever happens, walk out with your head up because you gave it your all. Tip: If someones laughing at you, give them a serious look and ask them, "if they have a problem?", because if you allow them to laugh at you, you're allowing them to walk all over you and that lowers your confidence and you don't want that. Society is harsh and you have to be harsh back.
