Called out

Just got busted at the Nature museum. I was trying to save a few bucks on admission, so I told the lady my daughter was 2...almost 3. My son walks up and says, "Daddy she's 3, she just had a had her birthday, remember?" I gave an uncomfortable chuckle and said, "ha, ha, your birthday  is coming up too right buddy?" I then gave a half grin to the cashier and said "its so hard to keep up with who's who". She didn't even crack a smile. So, I paid the full price. Sadly I even tried to use my zoo pass, that I didn't have with me but asked if she could call in or check on the computer. I guess its no wonder why museums ad the like are having budget problems with guys like me running around. I don't know some situations cheapness just feels right. I should have made my son pay. damn child labor laws. Honesty blows.
