cause it is talking about how they have known each other for so long but never really talked and that its good to let people know how u feel "It helps you to let off steam."
Peter. I suppose you miss your friends and all.
Anne. It isn't just . . . (She breaks off, staring up at him for a second.) Isn't it funny, you and I? Here we’ve been seeing each other every minute for almost a year and a half, and this is the first time we've ever really talked. It helps a lot to have someone to talk to, don't you think? It helps you to let off steam.(continued)
Peter (Going to the door). Well, any time you want to let off steam, you can come into my room.
Anne (Following him). I can get up an awful lot of steam. You'll have to be careful how you say that.
Peter. It’s all right with me.
Anne. Do you mean it?
Peter. I said it, didn’t I?
your welcome have a wonderful day
