I will second that. Your Skype friend is likely correct on all accounts. I certainly agree that Disney has not abandoned adults, and I am pretty sure that Stitch did not hate you, nor did the kids think you were being stupid, but instead were just having fun.
Keep a healthy attitude, my friend. Remember that as much as Disney is a corporation (and thus interested in profits at the end of the day), they are also above all an entertainment industry, and most of the cast do what they do because they love what they do. A smile, a high five and a thank you from ANYONE - whether it be child, adult or elderly is what tells them they have been successful and makes thier day.
