Dismantling of lock

Yesterday other than having difficulties in trying to understand and create a PERL program for a lab report, everything was ok till I reach my block.

Went to open the letterbox as usual but this time, my key got stuck & I just simply can't get it out or turn the key in the lock. It was at the locked position so I also can't close the letterbox. So I can't just leave my key there.

thus, I went to see if my mum's bedroom got light to see if she was at home & called her. Through the phone, I realized my dad was not back yet. Thus, I get my mum to find lubricating oil to see if it would work but I don't.

Thus, this time, I ran up to get tools. Spanners, to dismantle the lock. I'm glad my dad would ask me to help him in the past, to hold something for him, etc when he fix or dismantle things. So, that is why I managed to figure out what is needed to dismantle the lock.

Managed to get the key out eventually when the lock was dismantle but when we try again, the key was stucked again. Thus, my mum & I decided to fix back the lock at the unlock position for the time being till my dad buy a new lock to fix.

Think my uni friend, M, said I like v power, still can dismantle the lock. well, i might be able to do these stuff but only the basic. Think alot of things I do are only the basic only. Be it to cook, draw, dance, sewing, some handicraft...
