*sniff sniff* Don't know why today just feel so depressed.

I'm so stressed, every minute I'm thinking of the 'A' levels.

Last night, I messaged two friends to ask a question on a
particular subject. Till now they haven't replied yet. Hello,
please don't tell me "oh, I switched off my phone for the past few
days because I've been studying!" Like the two of you will...
Luckily I changed
my mind after SMS-ing them and called somebody instead. Phew.
When people get stressed, as in, in such a situation when the 'A's
are coming, is it normally like this? I felt so hurt, like they
don't care, or they care more about themselves [I have to study, no
time to bother about your question.]? Or at least if you don't know
the answer to my question, reply since it was clearly directed at
YOU with your name. 
That brings us to the question of SMS etiquette. The two friends
mentioned above.. aren't the only two who don't reply at times.
Sometimes, when SMSes are sent to some people, they don't reply at
all! Like say, it's a question: What time does class start
tomorrow? And if the receiver doesn't know the answer, he'll just
ignore it. Alright who's guilty of that?!
I think we should
just reply lah ok. Imagine the sender waiting and waiting... in
vain.
Sigh.
