Chances are, nothing scary is going to happen to you. But as the saying goes - better safe than sorry!
Staying safe home alone
- Check all the windows are secure.
- Lock the door from the inside.
- If someone knocks on the door, check who it is. If you don't know them well, don't let them in.
- If you have a back door, lock it before you go to the front door.
- Don't tell any caller, including phone callers, that you're alone. Tell them your mum/dad/enormous wrestling-champion big brother is asleep or in the bath.
- If the gas man or someone similar calls, tell him/her it's not a good time and to come back later.
Staying safe out and about
- Don't go down dark alleys or anywhere you don't know.
- Keep an eye on your drink. Even soft drinks can be spiked.
- Trust your feelings. If you feel freaked out, change your route or go somewhere you feel safe.
- Look confident.
- Set your phone to vibrate or silent so you're not a target to phone-thieves.
- Don't walk while you talk or text so you know what's going on around you.
- Before getting a lift, text the car reg to a friend or your parents.
- Before you go out, make sure your phone is charged and in credit.
Staying safe online
- If you have an social account such as Twitter, Instagram, Snapchat or Facebook, adjust your account settings so only approved friends can instant message you or see your personal details.
- When gaming, use a made-up name and don't be tricked into giving away any personal details.
- Don't have anyone on any IM contact list who you don't know in the real world.
- Learn how to keep personal info, like bank details, secure online.
- Treating anything any stranger says in chatrooms and forums with suspicion. Sexy 16-year-old boy asking when you lost your virginity = pervy old git sometimes. It's not worth the risk.
