Am I grown up?

Am I grown up? I think what it is true. I was glad when I bought pens on sale today. I am glad to have bought cheap pens. I saved up on my money. I am becoming like an old lady.

There's nothing wrong with saving 'a bob or two'* so you can use it when you need it for something you want.

* old British expression, meaning a fairly small amount of money, though sometimes used ironically to mean a much larger amount.  A 'bob' was a shilling in pre-decimal coinage, equivalent to 5p  i.e. £0.05, but at that time could buy much more than now.

"Am I grow up?  Am I growing up? I think so. I was happy today to buy pens on sale. I'm happy to get cheap pens. I saved a little money. I'm turning into an old lady."

Hope that helps. удачи вам!
