Okay, please do not be offended, (no racism intended) but I’ve noticed that Mexican Spanish speakers tend to talk really fast and I have a hard time understanding them, but I can understand other dialects just fine, (Cubans, Argentineans, Chileans, Spanish, etc.)
So my final two questions are why can’t I understand Mexican Spanish as well as other dialects and are Spanish speakers from Mexico known to have the fastest Spanish speaking dialect?
