You should try to find something that will allow you to spend some quality time together, like a stay in a hotel, a couple's activity, a concert, etc. If you can't find something like that, flowers are always nice.
-make a book with all the photos of you and your girlfriend / boyfriend.-poem.- teddy?
For a one year anniversary I would recommend giving jewelry. Not necessarily a ring however a nice necklace would work. It will depend on your girlfriends taste and what she likes for jewelry. Try to take what she currently wears as a reference as what to buy.
Propose her. There's a reason she has stayed around.
First year anniversary is when you have been with your partner for a year and you celebrate the long lasting relationship on the day you started dating: your anniversary
For a 14 year old boyfriend, you can buy him a mountain bicycle, to mark your one year anniversary.
Yes it is. By technicality, an anniversary is something celebrated one a year on the same date as the previous year.
say "HON, I LovE U" witch kiss and hug
If you and your boyfriend are aged 13 and 14 respectively, you can go mountain climbing on your one year anniversary.
Last year they celebrated the 100th anniversary, so their next one will be the 101st.
You get the date you and your partner stated dating and the anniversary is the same date the next year.
A 300 year anniversary is called a tercentenary. A 400 year anniversary is called a quatercentenary. (be careful with the spelling of this one!)
