Time goes so fast

Today it was is my daughter's birthday. She's now 15. I looked at her very carefully and I was wondering that how time goes flies so fast ! My daughter has becomed a teenager and a beautiful girl. I was very touched (or became very emotional) because it seems to me that it was like yesterday that when I held her in my arms for the first time...

(Nice Thought)

Time goes so fast

Today it was my daughter's birthday. She's 15. I looked at her intently very carefully and I was and wondered that time goes so fast where the time had gone! My daughter has becomed a teenager and a beautiful girl*. I was very touched because it seems to me that it was just yesterday that I held her in my arms for the very first time...

* The use of 'girl' is perfectly fine here, but 'beautiful young woman' or 'beautiful young lady' may express your sentiments better (since she has grown up and is no longer the little girl you once knew).

Good work!

Time goes so fast

Today, it was my daughter's birthday. She's 15. I looked at her very carefully and I was wondering that how time goes so fast !* My daughter has becomed a teenager and a beautiful girl {or young woman}**. I was very touched because it seems to me that it was yesterday that I held her in my arms for the first time...

*Another expression: "...how time has flown."

**We pretty much start saying "girls" from after toddler age and on, and we would start using "young woman" from after the "tween" years (around high school age [lycée])
