Commute by bicycle

I've got phone call from my husband who went the station before me.

Husband ："Train is late or not running. It seems there was fire somewhere on the rail. What should I do?"

Me："You can take the subway or bicycle."

Husband："I'll go by bicycle"

He came back home and go to work by bicycle. I decided to go by bicycle too. I followed my husband, then I arrived my office. I didn't late on the start time.

I commute by train everyday, so I've nearly gone back to home by train. But I remembered that I came by bicycle then I came back home by bicycle.
