While you're in the middle of what started out as an ordinary conversation, you'll suddenly realize that you're attracted to the person you're speaking with, though you hadn't yet seen it. Things might proceed very quickly if you choose to pursue them, but expect to have a rocky day or two midweek as you adjust to the strange new situation. Someone might get jealous this weekend. If so, do what you can to keep from escalating. Everyone will be a lot happier if they stay calm.
