Why does he send me funny videos?

So we are friend but recently we don't speak so much. He use to always be free to chat or at least text me at night before going to sleep if he couldn't reply to my messages... but now he has gotten really busy and I did text him the other day and asked where he has been and joked if he wasn't writing because he wants to forget me. He told me has been really busy and was coming home late as well...

Since that conversation, he has sent me funny audio and videos.. why? Like there is no hi or hello and when I write something about the video back which is usually a lol and a short comment on the video he doesn't write anything back. He has done this before as well when we use to talk every other day... I use to comment and he use to reply sometime not all the time but now he doesn't and I just leave it at that..

is he trying to tell me I am still in his mind. Is this a usual thing for guys.
