It's hard to keep long friendships. Some friends will be with you 1. your whole life. But 2., others may leave after a short time.
What should we do then? Just try 3. the friendships for as long as you can. If you're 4. upset about some lost friends, you can 5. to talk to them and ask them 6. it. If someone 7. not want to be your friend anymore, that is his or her choice. Also, it might be better to just have a few close 8.. You don't have to be friends with everyone. I only have about five close friends, but I know I can ask 9. for help at any time. Quality is 10. than quantity.

1. for 2. sadly 3. to enjoy 4. really 5. try 6. about 7. does 8. friends 9. them 10. better
