Pat, you are not alone. I feel dumb when it comes to the abbreviations... I just go with the flow. When texting my kids,(the best way to get a message to my children because they will actually respond to a text...), something like LOL (laugh out loud), JK (just kidding), Thx (thanks) or K (okay) they give me a bad time for trying to fit into the texting world.... So we can't win. I don't mind though, most of the time I just type EVERYTHING out (punctuation included)!
It took me forever to figure out that DH was dear hubby!!! LOL!!!
