Problem: He was a little clingy and did n't want me to go to work . I told him I 'll get him one if he behaved . Unfortunately , he said he wanted to follow me to work and to buy the harmonica ! Somehow , due to his short attention span ( not a good thing but good in this instance ! )

What is the man trying to buy for the narrator ?

A: A music player .

Problem: " I thought I 'd make sure you were feeling all right . " Sanzo 's eyes narrowed in a frown . Hakkai 's brow furrowed slightly as he continued , watching Sanzo intently .

What is the reason Hakkai 's brow furrowed ?

A: Hakkai was n't trusting Sanzo .

Problem: So I did , and he headed over from Mayfair to join us in a pub at Waterloo . The three of us spent until closing time chattering away about a load of stuff and we all had a really great night . Anyway , I 'll cut the next part of the story for the sake of boring you , but he got on the tube in the opposite direction to the one he needed , just because he wanted to chat more .

Why did they meet at a pub ?

A:
To have some drinks
