3 is the magic number

Today was all based around 3. I was supposed to pick up my Mum at the airport at 3pm, I had 3 people coming for dinner and I had 3 sets of invoices to get out. Unfortunatley my mums plane was delayed by 7hrs (yes 7!!) so I had to cancel dinner and never got the invoices out.
After my team letting in 3 last night and me going to my 3rd Chambers dinner, I guess 3 was yesterday.
