First time running standup as the temp lead and I blanked on my own team's blockers

Covered for my lead while they were out and ran standup for the first time. Froze completely when someone asked what was blocking my own ticket, the one thing I definitely knew the answer to five minutes earlier. Something about being the one asking the questions instead of answering them flipped a switch I didn't expect. Anyone else go blank in the exact moment you're supposed to know the most?
