DEAR HARRIETTE: My husband and I like to host parties at our home. Nothing fancy, but we do have people over almost every weekend in the cold-weather months. In the warm-weather months, we host barbecues in our backyard. Our friends do the same, so it always seems like we are at somebody’s house swapping stories and having a good time. We are devastated that we can’t get together now One of my friends suggested that we try creatingvirtualparties. I don’t have the foggiest idea how to do that. Do you have any ideas?
