[SERIOUS] How to detect if a door is opened or not ?

[akhileshbc]

When you're leaving the house and you've locked the door, vomit on the handle.

No....

There is a powdered dye that will stain hands a deep purple and is very hard to wash off, so you could dust that on the handle. That might just annoy him, but even that would be good.

That might be another good idea. I'll check that too. Thanks..

Watch Home Alone for ideas.

No. I don't want to make the house a mess...

Perhaps try something like this. Seems easy to build.

I don't know. May be it will kill him.

One day, pretend to go to work, have someone lock the door from the outside. Then sit in your hallway. Wait.

Yeah. That's what I'm doing for two days now. I can't goto college now, because of an injury in my left leg. I just hit my leg on the bed(strong wood. The bed doesn't got any scratches ), when I went to the bathroom, in the morning @ about 6 am. And my small finger in left leg got injured. The joint got misplaced. I didn't cared about the pain. And after an hour of resting, when I woke up, I fainted down.
Then went to the local physician (ayurveda) in local massage center, and he had done some work on my leg (oooh! that was painful ). Now I'm on rest

Maybe buy some cheap components, make your own makeshift alarm. Contact, Buzzer, LED (or LEDS), 9v Battery and some wire.

Put the contact magnet on the door, then the contact on the wall above the door. Wire it so when the contact is open, the buzzer goes off and an LED is lit. Im sure if he is 80 he will have no idea what is going on and will have a heart attack. Problem solved....


Ok well at least it might scare him and he will leave?

Thanks... I'll try that too...

Naked.

Seriously. He'd never go near you again.

No...
