Conundrum

At the airport, two cousins say farewell.

"I hope you do well", the younger says to his elder cousin the traveler.

"Well, you know I only need coffee", the traveler says. He doesn't need much.

"Yeah, well I mean better than that", the younger says, having seen his cousin go through some hard times and sincerely wishing him well.

"What's better than coffee?", asks the elder with a laugh.

A shrug.

"See, that's the problem now isn't it?", responds the traveler.
