My house nearly burned down this evening!!!

I smelt this weird smell (not unusual in our house given my brothers always doing weird things with gas and stuff), so shut my bedroom door to try and shut it out. About 20 mins later, my brother shouted 'Sarah, you really should come and see this!...no you REALLY should come downstairs NOW!' I opened my door and the whole house was filled with thick smoke

Went downstairs and a the plastic bag holder thing was up in flames (what was really odd was that there was no signs of anything starting a fire, it just seemed to have spontaneously combusted

) Just as we got to it, it was literally just starting to start on the wood pile, so lucky we werent a couple of minutes later really!! When we'd finally got the fire out properly, opened all the doors and windows, the smoke took ages to clear.
Then our parents got home...lets just say they weren't too amused!
Everything stinks of burning plastic now

The scary thing is that the house was really full of smoke and the smoke alarm didnt go off...it could easily have happened at night or when noone was at home! I'm a bit scared to go to bed now tbh.
Apart from that and physics revision not going brilliantly, today hasnt been too bad!
