Could you correct my diary?

I called one of my friends on Skype. It’s been for a while.
He has a son who I just know the name who I only knew by name. I haven’t hadn't met him before.
During Skype, his son appeared in the video.
He is too adorable.

I imagined if I were somebody’s mother I would spend my life lively happily (?). "spend my life lively" の意味が分かりません。
Skype chatting with him and his son gave me a fulfilling feeling day to me.

My friend and I went to Tokyo and Tochigi prefecture by bullet train

My friend and I went to Tokyo and Tochigi prefecture by bullet train from November 3rd to November 4th.
It was one night, two days trip.
We left home at 6:30 in the morning. We arrived at in Tokyo at 9:30.
At first we went to Tokyo Messe to see Tokyo Motor show.
Many new type of cars were exhibited. I like Mazda’s sports car. It is a very sophisticated design.
I think Hybrid cars will become the mainstream of the automobile industry.
American cars didn’t take part in the event.
Then we went to a German Fair in Aoyama Park.
My husband wants to go to Germany to take pictures of steam locomotives again, so we collected sightseeing pamphlets.
There were a lot of beer and sausage booths,
Thaw the price was twice two or three times more expensive than Germany.
I couldn’t afford to eat them.
Next we went to Omiya city to meet his friends. We had a dinner in at Chinese restaurant.
We had a good time.

On the second day we woke up at 5:45 in the morning.
We rented a car in Nikko station.
At first we wanted to see Nikko Toshogu and the colored leaves.
But we got stuck in a traffic jam. Then, the parking lot was full.
If we walked from the Nikko station to Nikko toshogu, it would take about for an hour.
I don’t didn't have enough stamina to do it.
Nikko Toshogu is a Shinto shrine situated in Nikko, Tochigi prefecture.
The shrine is was listed in 1999 as a world heritage site.
It’s the mausoleum of leyasu Tokugawa who founded the Tokugawa Shogunate in 1603
and passed away in 1615.
We decided not to go there and go went to Ryuokyo instead.
There was were two small waterfalls in the valley.
We walked around there. It was really beautiful.
After that my husband took pictures of a steam locomotive until sunset.
It ran from Nikko to Kidogawa onsen station. I was bored to death.
While he took pictures of them, I was taking a nap at the car.
We returned home at midnight.
It was a tiring trip.
