1. Friends are companions throughout a lifetime, possible. One may not have a sibling to get along with but a friend that could understand and support better. Friends are there for you to rely on both in good and bad times.
2. If you have the ability to put aside differences and to respect your friends beliefs than friendship it’s possible.
3. You can be a friend to someone as long as certain boundaries are acknowledged and respected. How far? As far as you feel that your friend would do the same for you...
4. E-mail and nowadays devices may be able to sustain personal relationships for people that live in different countries/cities or continents. But sometimes a friend is needed right beside you and e-mails or phones can’t replace that yet!
5. Friendships evolve with time. Growing up, getting older and wiser may affect the nature of friendship.
