A Realization?

I had a strange dream yesterday. It wasn't really strange - it was more of a realization. I'm not sure what brought it on, maybe it was something that happened yesterday or maybe it was just one of those random dreams. Anyway, that dream had something to do with losing touch with certain friends and hearing about their life from others. That is one thing i'm really scared of, so that dream was kind of like a nightmare. I'm scared that after we all leave school, we'll lose touch. I'm afraid that i've already lost touch with certain people.
I know that there are people i was MUCH closer to before and now all we say is hi and bye. I hate that and i'm sorry. I really truly am sorry for not keeping in touch. I know people say that if he/she doesn't bother to keep in touch, then why should I? That makes me feel sad for the person. Their arrogance is going to cost them a friend. I wish people could realize that it doesn't make a difference who starts a conversation or sends an email/sms/IM first.
There are people in all our lives who used to be one of our close friends - and now? Do you know where they live, where they are, how they are? If you still have a hello-bye relationship, do you remember simple things like his/her favorite colour, his/her hobby? There's still time, it's not to late to contact old friends and to increase your relationship with the hello-bye ones.
Maybe you think that you'll send XYZ a general email enquiring about his life those days. Then you think i'll do it later. Later becomes tomorrow. Tomorrow comes and tomorrow goes , the distance between you two grows (that rhyme was unintentional!). Eventually, that email will not get sent. It takes 5 minutes to send an email. Take the time out to send a couple of mails to old, forgotten and lost friends.

PS : I know this post sounded a bit repetitive, but i just wrote what i felt at the moment...
