M:Can you tell me some interesting activities in the library?
W:Yes.We offer a lot of activities and the most popular one is Story Time for children.It takes place in the Children's Room on Thursday mornings at eleven.
M:Isn't there a family movie night?
W:Yes.But it's not at night anymore.We used to have Family Movies on Fridays when the library is open until nine,but now we have a different activity at that time,so we had to switch Family Movies to the weekend — Saturday afternoon.
M:How much do you charge for the movies?
W:They're all free.The movie starts at 2:30 in the Reference Room.
M:And what takes place on Friday evenings?
W:We've just started a weekly Lecture Series.We have a different speaker every week,and the lectures cover all different kinds of topics.
M:That sounds like something I'd be interested in.When does it start?
W:The lecture starts at 6:30 in the Meeting Room.But you'd better come early,or there will be no seats left for you.
M:I got it.Thanks.
