Hacks By Me:
1.Use A staple remover to get keys on keyrings
2.Use A dust tray in a sink to fill over-sized buckets.
3. did your mom get the wrong batteries for your remote, just put them in like they were the correct ones, then put some tinfoil in to fill the gap, the battery is the same voltage, and same chemical, so it will work.
4. are you cutting onions? you can either put the onion in the freezer for 15 minutes OR simply breath through your mouth, no more crying over cutting onions.
5.If you can use accented/foreign (Any letter not in the english alphabet and is not a punctuation mark) letters in your password, most people dont even know how to use them, so nobody will guess your password correctly.
