W: Hi, Missy! It"s Delilah. Do you want to go shopping at some shops downtown this afternoon? My boss called me this morning and he says they"re not opening the store today. Thank goodness! I haven"t spent a day away from the cash register in weeks! There was a robbery last night, so the police are there today to investigate. Well, I have the day off. I"m going to call Marina and Joyce next to see if they are able to go, too. The four of us haven"t had a girl"s day out in a few months; it"ll be nice to chat and catch up. I think Marina is trying to get pregnant. Anyway, we"ll find out more this afternoon. Call me!
