Have আপনি ever asked one of your teachers for their যন্ত্রপত্র address?

i don't have to. Their emails are পোষ্ট হয়েছে on our school website. Also i can probably find them on ফেসবুক

No, but my substitute teacher emailed me once. How did he get my email? Who told him? I haven't পোষ্ট হয়েছে it anywhere online, I swear. Seriously, how did he know?

Anyway, he was a creepy teacher. He sent me this weird thing with my name flashing all different colours when I pushed a button. He must have spent ages making it. And then he thought I was really depressed, so he sent a long letter trying to cheer me up. I wasn't depressed, though, and his letter was ...strange. <_<'

I did... to complain.

Well their school emails are প্রদত্ত to us, so we don't have to ask. I have a few of their private emails because our server goes down a lot and I have to যন্ত্রপত্র them papers, and I've messaged a few on ফেসবুক about assignments, but we are not allowed to friend them until we graduate. And I know some of their cell phone numbers.
