My two siblings are real last minute types at Christmas, whereas I'm more organised. More uptight you could say!
We usually do a group gift for our parents. They weren't coming up with anything so on Saturday I found tickets to a comedy gig they'd like. I posted it in our siblings Facebook group and everyone said yes. On Sunday morning I found tickets for it, sent them a screenshot and asked for the money of their share. Its 20 pounds each but it's too expensive for me to book it before pay day unless I at least get some of their share sent to me.
No one has sent the money so I haven't booked the tickets. I feel unreasonable but AIBU to think it's minimal effort to simply send me the money
