Rewind, Repeat

So seriously--how many times can people have the same exchange of dialogue? Whenever I catch myself engaging in one of these conversations, I want to shoot myself.

Person 1: Hi! How are you?
Person 2: Great, you?
Person 1: Great! The weather is great!
Person 2: Yeah, but I think it's going to rain this weekend.
Person 1: Oh dear. It always rains on the weekend! Ha ha.
Person 2: Ha ha.

OR...

Person 1: Hi, how are you?
Person 2: Great--it's [insert day if its "Hump Day", Thursday, or Friday]. We're almost at the weekend!
Person 1: Ho ho!

Alternatively...

Person 1: Hi, how are you?
Person 2: Well, it's only [insert Monday or Tuesday]. Have a few more days to go before the weekend!
Person 1: Ho ho!
