Is it right to say?

- The day started with surprising
My friend just turned 20 today, and me and her friends went to her house and surprised her.
So I wanted to write in Twitter how my day started.
We started the day by surprising my friend.
Is it grammarly correct to say: started the day by surprising...
Do you mean omitting the subject of the sentence? If you start your sentence with a capital letter it is OK.
When the subject is understood it can be omitted. Especially on things like Twitter. You are narrating your own life.
Got up today. Made some toast. Took a shower. Drove to work.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
I thought you were breaking into a song from "Grease."
