How to write a thank you message to an elder who gives a gift to someone you meet for the first time

Let me see what I give you. If it is very useful, say: Thank you for (what). This is very helpful to me. It really helped me a lot. I don’t have anything to do with you, junior. I can give it to you. I can only say thank you and give you blessings (if you want to add some blessings later, you can write it yourself)

If it is not something very helpful, just say: Thank you for (something), I I like it very much, and I think I will cherish it. I hope it can help me one day. Thank you. (It’s OK to just write something by yourself below. The elders I just met won’t have too much with you. For communication, you just need to give him a good influence and it will be OK)

If you think it is possible, then adopt it. If not, I hope you can find a better one.
