nah... they only end up getting bored of you 10 years later and you have to learn to live by yourself after that... if you want a best friend get a dog
Well that's true but you'll also get chances to meet some new people instead so there's no need to worry about that. ^-^
I do agree with Bunny-san though, you should try to make yourself as strong as possible as an individual. In the end we'll always end up alone so better get comfortable about it.
