People think bringing your 15-year-old sister to 21 and over clubs is a bad thing. But what do they know. They’re not Lindsay Lohan. She tells Life & Style that it’s fine and not to worry. Ali parties responsibly. That means no double-fisting.

“She’s tougher than I am,” Linds told Life & Style. “She has a good head on her shoulders. Maybe it was different for me because I didn’t know what to expect and it just happened really fast. I didn’t have a big sister.”

Already, Ali’s got one thing going for her because she knows when to call it a night and do her homework…

“She’s really good about that,” Lindsay says. “If I’m going out late, she’ll go home early.”

See? The only reason Lindsay turned out the way she did was because she didn’t have a big sister to show her the ropes. Ali does. She’ll be learning all the tricks in no time. For example, if you want privacy, you snort lines of coke IN the stall and if you want to drink but don’t want people to know, hide the vodka in a water bottle.

Also, a note about how Ali goes home early to do homework. That’s not a big deal. She’s homeschooled. Which means her teacher is Dina Lohan. It’s like being taught life lessons from Harry and Lloyd from Dumb & Dumber.
