Vivienne had been sitting for a while, when she heard someone else join the group. "SURPRISE!!" she yelled instinctively, not even seeing who it was. "Oh wait, sorry wrong person! We've got to wait for Arisa." Vivienne laughed, running over to the person. But as they turned around, she realised that it was the right person. "Oh um, Arisa! I mean, um, SURPRISE!" she said, throwing her hands up and smiling embarassedly.
She began to shake her head when Arisa told her that she hadn't needed to go to so much trouble. "No no, it was no trouble at all! That's just what friends do. In fact, I had quite a bit of help from some friends.." she said the last bit quietly, pulling out her wallet to check that she'd be able to pay them in cash. "So yeah.. um.. Happy birthday!! Hoorah." Vivienne laughed, realising that she should probably stop talking now.
