Have u ever put a lot of deep thought into something?

Like just a min ago. I was thinking do I ever appreciate what others do for me....and it's like ok I am a giver no matter what mood I am in and if I can help someone I will. And I have moments where I feel no one gives a rat's a@@ what I do and never appreciates it more so...but...
But....I have to ask myself well do I appreciate and show my appreciation for what others do for me....
and then I am thinking also
What does showing appreciation really look like...like how do you know when so.eone appreciates what u have done for them?
Lol too deep of thinking I am sure but this is a for instance tho!!
