my living room is fraught with danger now. omg. there were warning signs minutes before this occurred. my mum was back for lunch at 1230 and the baby chair that me and her would always be using as a table (2nd pic, top right) was at that exact location where the tile spilt was. then there was a series of cracking sounds that seemed to originate from the unit above ours. but upon closer listening, these sounds were from the floor. at this point, i was in the comp room looking for maple equips at free market, and i just told my mum to evacuate to the kitchen IMMEDIATELY. (i was like shouting and barking at her la. zzz.) and a couple of minutes later, this happened. my parents will have to pay big bucks over the re-tiling works i suppose. repairing works are now being carried out by my dad to reduce the danger as well as to await cementing of new tiles.
