You went one time, sure you're interested to see what's going on. I have 3 kids that have 2 activities each, some activities are 5 or more days a week. You see the same damn practice many, many times, day after day. When I go to one of the games I'll watch the whole time, but for a practice I'll surf Getbig instead.
Easy to judge when you go once, stick with it daily, year after year and see if you don't surf the Internet while you wait at a practice.
