是非一緒にお出かけに行きたいんだけど、実は昨日と今日は引っ越しの荷物が届いた所で、子供達もとても疲れてしまっています。明日はゆっくり過ごさせてあげたいので、残念ですがごめんなさい。別の日にお会い出来るのを楽しみにしています!
We would love to get together, but my children are also very tired as we received our moving packages yesterday and today.
I want them to be relaxed tomorrow, so I'm afraid we can't make it.
We look forward to seeing you another day!
