Making new friends

It is not recommended to exchange telephone numbers with your friends.

Text:
Be yourself!
When people meet for the first time they want to seem perfect. But friendship should start from the truth. Show all your real emotions and feelings, and people will like you the way you are.
Visit places.
Go out. Meet new people. Sitting at home, you will never meet new people. Go to the park. You will meet people playing football and having picnics there.
Find a soulmate.
If you want to meet people with common interests, you can choose a place to go. If you like sports, you can join the Sports Club. If you enjoy reading, then the Book Club will be the best choice. If you are interested in active leisure, join a walking group.
Get to know the person.
Learn more about the person you met. Talk. When people communicate, they find common interests, hobbies and people they know. You may find that you share tastes in music or have nothing in common.
Be a good friend.
True friends are always there when their friends need help. Friends must know that they can always rely on you and trust you. Never talk behind your friend’s back and tell your friends’ secrets.
Stay in touch.
Once you make friends, do not lose touch with them. Follow each other on social networks and take phone numbers. Agree to meet somewhere next time.
