Nope, but I've been there. Don't think I picked up any speaking habits, tho. I tried all the above tips, and I dunno if I'm doing it wrong or my wife is just having fun with me. The more I try, the harder she giggles.
lol OK, understand. Well, that accent carries past Baltimore and I've heard it in the MD/PA/DE/VA/WV area as well. It really sounded like maybe you have a Baltimore "O" as we call it, it sounds like A-ow. Don't worry, I have it a bit as well. But I can pronounce Ola. Maybe, if she's giggling, she likes the way you say it? Maybe she's flirting with you? Polish women do flirt with their husbands, you know. And we do it in little ways that some guys don't catch on to. ;)
