Irresponsible pple

i sent out like 50+ sms last night to ask those newbies who attended this sem's class if they wan to continue with advanced beginners for next sem but instead of sch it's gg to be outside studio cos we cldn't get studio in sch. mind u 50+ sms. How many numbers do i have to key to send those messages? my msg goes "Hi all! Yen Lin frm Jazz here. Please reply me this msg asap...blah blah blah". How many response do i get in return? Less than 20! I dun mind smsing them but cant they jus reply? How much does a sms cost? Jus a yes or no answer is that very difficult??? Bloody pissed! The workshop also liddat. Irresposible pple who signed up then i smsed again each and everyone to remind them, din get their reply too. End up the turnout was super poor. Can't they jus reply me they cldn't make it? really makes u feel sick and tired. i cant wait to step down. the worst committee i've been in. Of course i'm not saying my comm members are not gd or anything but it's the nonsense(or worst still not even nonsense but nth at all, not any kind of response) frm these pple. ROAR!
