I'd definitely consider participating.
. And I just want to say to anyone else that would like to participate. Do it for yourself, with no expectations in return. It's kind of like this, just because someone doesn't love you the way you want to be loved, doesn't mean they don't love you with everything they got. Personally, I don't mind looking at photos over a smile box. Smile boxes can be intimidating to some, I get that. If smile boxes are what it takes for a thank you, I'll happily help anyone with theirs.
