If you could send me a Pug Life collectible today, remind me to send you one of my spare Hotdog Dog collectibles tomorrow. Damned thing only allows one collectible to be sent to one specific individual per day, or I'd have sent you loads of collectibles already.
Hi, T. I'll send you some collectibles, and I wonder if I can get some of your spares. Starting today, I can complete your Net Noob collection by sending you what you need. Could you send me a spare "Internet On CD" collectible to complete mine? Also, later I can send you one of my spare "Hotdog Dog" collectibles to complete your "I Has A Hotdog" collection if you send me a "Pug Life." Since you can only send one collectible to one person per day, this is the best I can do for now.
