What’s wrong???

Since past few days I’ve been observing something strange & unexpected going on in my life. I don’t know why but usually these days I’m getting unexpected responses(Or you can say no responses at all) from people around me. I have a good habit to take some time & pass on my good wishes on any special occasion to the concerned person, so doesn’t matter how small the occasion is. I always remember those dates & make sure to wish them. The only logic behind this behavior is that, I know it always feels nice when your cellphone beeps specially on your birthday or so on… I do it with literally no expectations, as I have been doing this since long back & obviously what can I expect from a old friend whom I’ve not seen say almost more than a decade.
But since past few months I observed that I was not getting any response from the person I just wished. Everytime I assumed that very obviously he must be busy on such a special occasion but man come on tell me do you celebrate your birthday for 15 days?? Huh!!!
K lem me tell you one incident happened recently. Few days back,one of my engineering mate messaged me on the ORKUT after long long time. He is out of the country say for 1 year. I happily responded him & asked me how was going… as expected there were few messages exchanged. After say 1 month, I wished him on his birthday through ORKUT only. But till this time, I have not received any response from him. Anyways I assume he might have missed my message amongst all other birthday wishes.
Ok other incident, I wished my cousin on her birthday with an early morning SMS… No Response. So I called her after say 2 hours, I found nobody was answering the call. Ok so I got the answer that she forgot her cellphone But anyways I’m very sure about her that she will not overlook me, so I’m happy

So in all these happenings I’m not disappointed but definitely I’m concerned as I’m asking myself “What’s wrong on my behalf? What’s making people around me behaving like this?” Probably, 2 possibilities :
1. They don’t feel like responding as they feel its just a formality
2. They might be considering that I’m so understanding that even if they don’t reply, I will assume that they are busy

Anwyays whatever it may be, I’ve decided to keep a close tap on my behavior to check out if I’m behaving oddly That’s the best thing I can do…
