Bro there are A LOT worse things than watching your parents party. I grew up going to partys every weekend with my mom and stepdad because they couldnt get a babysitter. I was around drinking, weed, and from what I know now coke. Kids are smarter than you think, and it may have just been me, but I grew up accepting that partying was a regular thing for my parents. It never bothered me, and I never started drinking and doing drugs at a young age just because I saw what they did. To this day I dont drink and I wont fuck with coke. I say its alright to party around your kids, as long as you dont get too wasted and dont drive with em drunk. If your kids love and respect you, then they will respect what you do because your thier father. Like I said, kids are smart.
