<human>: Can you summarize the given text in a few sentences?

I (F17) was sober sitting two friends of mine while they were on shrooms. My friend gave me the guy's number who sold them to us (M19) in case of emergency. He ended up coming over and hung out for a few hours. He seemed funny but we didn't talk much. I didn't say much when he left, just bye and thanks for coming over. I want to text him and say:

"Friend A gave me your number in case anything went wrong the other night. You seem like fun, I'd like to get to know you. :)"

Is that awkward because he might not be sure who is texting him? Or is it weird that I'm texting him period? Is there another way to approach him? Will
<bot>: (Not that this is very long.) Got cute guys number from friend, not sure if it would be weird to text him.
