You know what, I dislike kids that try to ruin a surprise. As a parent, I try very hard to make things fun. I wrap and hide the presents and then wait til my kids are asleep, sometimes it's really late, then I put them under our tree. Don't wreck our fun, be patient and wait!
Well, my mom needed my help to order an airsoft sniper rifle for me this year. So, I kinda know that I'm getting that. I also know my little brother bought me airsoft BBs because he would not let anyone help him wrap it, so it's pretty obvious what it is.
One year my sisters & I opened all our gifts up very carefully without ripping the paper & taped them back neatly so that our mom (I guess) couldn't tell. They were great gifts but it was the worst Christmas ever. We never did that again. Part of the excitement of Christmas Day is the build-up. Be patient & ... Merry Christmas.
