Wanna Trade?

Life goes on.
At work one my customers, Mr. H, came from his "apartment" over to ours. My door is the first one. He rushed in, stopped to a sudden halt at my doorframe, I looked up and found him grinning enthusiasticly, holding out his arm, showing off his IKEA-watering can and asked, "wanna trade?!".

I once loved the color pink, didn´t do so any longer and brought my pink IKEA-watering can to use it at work.
Not such a good idea after all, since that stupid thing is used by my colleagues as well and hence found it´s place clearly visible for everyone - including me! - at the side of my desk.

Till today!
I said, "sure, I like green way better :-)"

Him: "Really? I loooove pink, could be even pinker for me!"

That left me confused.

I know this man for seven years. I don´t see him every day, but each time I see him he wears a green sweater.

Really, every time.

He loves pink?! And gives me his green...???

Well. ...?

Aw, well. Now I have the IKEA-watering can after all! Ingo didn´t want me to add a green one to my red one at home, since we already have so much stuff.
