Too much information
This family thought picking up their mother at the airport after spending so much time apart would make a nice gesture, but when you make a welcome home sign, a simple “welcome home” does the job. The middle sign is quite unnecessary, if you ask us.
Then again, there are three of them – a father and two kids, and they probably needed a sign for each of them, so although the middle sign is redundant (to put it nicely), they couldn’t really give it up. What they could’ve done instead, if they wanted everyone to have a job holding something, was get her a bouquet of flowers or balloons.
