Lasagna hates me!

So, I would definitely say that I am not a gourmet chef but I can usually make dinner without ruining it with the exception of Lasagna. For my mom's birthday back in August I thought that I would be nice and invite everyone over for dinner and make lasagna. Well when I was making the sauce I was adding salt (we had a salt grinder) and the lids popped off and dumped all the salt into the sauce I tried to scoop out the salt because it was too late to start over but it didn't work so well and was still pretty salty. Then yesterday I invited my parents over for lasagna because we always have tons left over if it is just me and Adam eating it since it makes such a big pan. My Mom had mutual but she said my dad would still come over so that she didn't have to worry about making him dinner before mutual. So I got off work at 5 and my Dad was coming over at six thirty which was just enough time to make the lasagna. I had Adam start boiling the water for the noodles and cooking the meat before I got home so the food would for sure be done on time. I was so proud of myself for being so prepared and that the lasagna would definitely be done on time. I must have been feeling a bit too confident because that is when disaster hit. I was layering the lasagna into the dish and started to smell something really bad. At first I thought it may be the cheese but I smelled the cheese and it was fine. So I had Adam smell it and decided that something was definitely bad. We finally decided that it was the tomatoes in the sauce. So I had to throw all that food away and figure out something else to make which was not an easy task since all the meat I had was frozen and my Dad was going to be there in 45 minutes. I ended up making chicken and mashed potatoes and I have officially decided that lasagna hates me.
