Question: Context: 'Awesome! That does sound like a deal. I wish we had more firewood to split because I am afraid it might get cold.' 'I agree. I am feeling generous and I did buy a new axe for this camping trip. So, I could stick to the prior agreement and just work a little harder to find some dry trees to chop.' 'I appreciate your generosity 🙂 I think that bringing your axe would be a great idea! Also be sure to pack warm clothes and extra blankets! I'm sure we will both be fine'
