Every guy knows how annoying a sister can get. If she's elder than you, she'll give you faaltu gyaan . If she's younger than you, she'll keep bugging you all the time. But no matter how irritating sisters are, they are undoubtedly the best things to have ever happened to us (though we might not admit it in front of them).

Here are 20 reasons why every guy is lucky to have a sister.:

1. You get the most honest opinion on everything.

Your friend: " Awesome jeans bro!" Your sister: " Are you out of your mind? Why are you wearing orange jeans?"

2. She has your back all the time.

Out on a late night drive with your girlfriend? Just call her and she'll cook up an awesome story to tell your parents.

3. You'll have enough 'awesomely silly' photos to LOL on.

She'll take silly selfies with you. You may hate it now. But over the years, you'll love the silliness. Thank God for sisters!

4. Need your dad's car keys? Turn to the sister for help. There's nothing she can't brainwash your parents into.

Because parents generally trust daughters more.

Not quite sure of this one, but it may just work for 0.73% of the male population.

It's a female thingy. They do it best... Your GF, your mom, your sis. Too many females. You don't need to interfere.

17. If you have an elder sister, it's like having another 'cool' mom.

She always pushes you to do better. Be it making that career switch or taking that film-making course abroad.

Because you'd be a pro at handling tantrums.

Life is so much fun when she's around.
