1. Sincerely -
Meaning: I really appreciate what you did.
Example: My mom sent me a huge bouquet of flowers for my birthday.
Mom: I hope you like the flowers.
Me: Thanks a lot (I really love them and appreciate you sending them).
2. Jokingly -
Meaning: I’m teasing you. I’m not really thankful but I’m also not upset.
Example: I’m on a diet so I’m avoiding desserts. Karen brought over freshly baked cookies.
Karen: I know how much you love cookies so I made these for you this morning.
Me: Thanks a lot (this is ruining my diet but I appreciate your thoughtfulness).
3. Sarcastically -
Meaning: I do not appreciate what you said or did. I wish you hadn’t done it.
Example: My friend Lisa accidentally told my boyfriend that I’m planning on breaking up with him.
Lisa: I didn’t realize what I was saying. It just came out!
Me: Thanks a lot (you really messed things up for me; I wish you’d kept your mouth shut).
