Is that allowed on the internet?

So I was talking to my 83 year old mother and telling her about this blog. I read her a sampling of the posts and she was quiet while I read them to her. When I was finished she said: "Hmmmfffff, I didn't think you could use language like that on the internet. Is that allowed?"

I explained to her that it is allowed, so she said: "Well, I wouldn't think that was allowed. It's rude. It shouldn't be allowed. Can just anybody see that?"

Me: "Yes, Mom, anybody can see it who has an internet connection."

Mom: "Well you shouldn't be talking like that on the internet. I don't think it's very nice. Can't you think of some other way to say what you have to say?"

Me: "It's not like it's kiddie porn, for God's sake!"

Mom: "What? I'm just saying I rather you didn't talk like that. It's not necessary, is it?"

Me: "Nobody knows it's me."

Mom: "Still, I know and you know. It's not very ladylike." (this is usually the part where she throws in: you weren't raised like that...thank God it didn't go that far!)

Me: "Ok Mom, I won't do it again."

Mom: "Alright. Goodnight"

Me: "Goodnight."

I'm thinking: Holy Shit! Last time I tell her anything!
