Balloons

While solving a case study on event marketing we came to the following problem: Why have we never got any balloons in winter? Is it a technical problem or rather a life style issue? There might be complications with the low temperatures and the helium. Or just with the changes of temperatures when you take the balloon indoors. Or it is just because you could loose the balloon easily when you wear gloves. Or maybe people just don’t like balloons in winter.
I don’t know. Do you? Any suggestions? Tell me!
