I wouldn't say bowling with your Dad can count as a bad night. Scores might be low, but Dad was there with you.
Enjoy your next outing.
Amen to this, wish my Dad could bowl without hurting his back.
If you start having one of those nights, start drinking..heavily.
seriously though, sometimes once you have been through the bag once, chose a ball that doesn't get much play, and just work on findng a shot. If you are already gonna hit 140 and lower, won't matter, make the most of it, never give up. if you salvage 1 game for 160+, but the last three shots were really close o there because you found a new line, you can atleast take that out of the night. if you just can't find anything, well, you'll get a few more pins of handicap next week.
