gardens in London that you want to go and see. Then weâll work through your list together over the next few weeks.â
Caitlinâs eyes grew round as she looked at Erinâs phone. âBut this is the latest...â
âI know. Iâm a total tech junkie,â Erin admitted with a grin. âThey give me a hard time about it at work because I always get the newest version on the very first day it comes out. I have been known to queue up outside the shop at stupid oâclock to make sure I get one.â
âBut if I drop it...â Caitlin looked worried.
âThen, yes, the screen would probably crack and Iâd have to get it fixed, which would be a pain. But Iâm trusting you not to drop it. Youâre thirteen, not a baby,â Erin said briskly. âOK. Weâre going to Kew instead of trampolining, so weâre taking a different route from our original one. Youâre looking for the District Line, which is the green one. Go and have a look at the map on the wall and tell me which station we need to change at to get there.â
âOK.â Caitlin carefully put Erinâs phone in her pocket to keep it safe, and went over to look at the map of the Tube⢠lines on the wall.
âOh, my God. Sheâs talking to you like Iâve never heard her talk to my mum or to meâeven in the days when she was little and seemed to like being with me. How did you do that?â Nate asked, looking impressed.
âI was straight with her,â Erin said. âI told her Iâd been in the same place as her, so weâve got something in common. And I just hit lucky with the garden thing.â She wrinkled her nose. âSorry. Thatâs going to be a bit difficult for you. I promise I didnât do it to score points off youâit was just the first thing that came into my head.â
âI know youâre not scoring points, and itâs fine. More than fine.â Nate looked relieved. âYouâve just given me something I can do for her. She can have her own patch in my back gardenâand my mum loves gardening, so it gives her something in common with my mum as well. Youâre amazing, Erin.â
She lifted both hands in a âstopâ signal. âIâm not amazing. Iâm just me. And itâs very early days. Itâs not all going to be plain sailing and youâre still going to have fights. But this is a good start and you can build on thatâbecause now you both know youâre on the same team, right?â
âYeah.â Nate swallowed. âYou have no idea how good this feels.â
âItâs good for me, too, knowing that I can stop someone feeling as bad as I did at that age,â she said. âSo you donât owe me anything, OK? This is a situation where everybody wins.â
Caitlin came back and recited directions about where they had to go and where they had to change lines.
âGreat. Youâre in charge of getting us there,â Erin said.
âButââ Caitlin looked shocked.
âThe best way to learn your way about on the Tubeâ¢,â Erin said, âis to just do it. If you miss your stop, donât worryâall you do is get off at the next station, cross to the other platform and go back the other way. Thereâs only one rule.â
âRule?â Caitlin looked wary.
âI donât have many rules,â Erin said, âbut theyâre not negotiable and theyâre not breakable. If you get on the train and you end up separated from me or your dad, then you get off the train at the very next station and you stay right there on the platform where you get off. Then we can find you easily. Same as if I get on first and Iâm separated from you, then you stay where you are on the platform and you get on the next train in exactly that placeâthen when you get off at the next stop youâll see me as soon as you get out of the
