DH and I have a totally different way of talking when we're alone together--we use abbrievs, Spanglish, weird nicknames and random words/sayings/inside jokes that we find funny. If anyone overheard our private conversations, I would be embarrassed based on the weirdness factor alone, and I know we'll have to quit once LO is here so she's able to string together complete sentences someday. Do you and your SO speak your own language, or are we just weirdos who spend way too much time together?
