I Wish I Had a Childhood Friend Like This 61 「Our parents said they aren't coming home today. Ehehe, it's been a while since the two of us had an overnight stay, hasn't it?♪」
Technically it's faster/a little less clunky just to translate it as "It's been a while since you slept over", but the raw text is along the lines of "with the two of us", so I tried to preserve that with "since the two of us had an overnight stay".
Edit: Was looking again, and based on the flow of the picture it looks like the text in the upper right panel is meant for our guy. Changed it from "My parents said" to "Our parents" to convey it better.
