I'll pencil it!

I have always thought that one of the best thing about speaking English rather than Italian, is that English has shorter words, sentences, periods.

I.e. I'll pencil it on my diary (7 words, in total 21 letters)

In Italian?
--- Lo scriverò con il lapis sulla mia agenda (8 words, in total 35 letters!!!).

And I'm not sure that the Italian sentence conveys the wide range of meaning of the English one.

Last but not least, I do love the stress given to "I", the self-person that English always show.

I'll pencil it (the stress is strongly based on the subject, the object comes later).

Lo scriverò (the object of the sentence comes first and the subject is not stressed).
